Are Democrats’ Stunning Midterm Upsets in Deep-Red States a Blip—or Is Their Map Expanding?

Before Tuesday, the last time Texas voters elected a Democrat to the U.S. Senate was in 1988. For South Carolina, it was in 1998. And for Kansas, it was nearly 100 years ago, in 1932. Now, all three will be sending Democrats to the upper chamber, shattering decades of Republican dominance in the deep-red states.In the weeks leading up to Election Day, polling had indicated that voters were more likely to support Democrats over Republicans in this year’s midterms. But the polls ultimately underestimated the magnitude of the blue wave—what some have dubbed a “blue tsunami”—that swept over the country on Tuesday.It’s typical for the sitting President’s party to lose seats in midterm elections. The scope of Democrats’ victories this cycle stands out even in the context of that historical trend, though—while not all the races have been called yet, the party is expected to secure the largest majority in the U.S. House since it won 257 seats in the 2008 presidential election, and has flipped seven seats in the U.S. Senate so far.Many political pundits have characterized this year’s midterm results as a “repudiation” of President Donald Trump. The President has a historically low approval rating, driven in large part by Americans’ dissatisfaction with how he has handled the economy and foreign affairs, particularly the war in Iran.But the question on many people’s minds now is: was Democrats’ success in these staunchly red states a blip, or a sign that these states will be more competitive in future elections?Democrats’ wins went deeper than one-off racesJames Talarico has emerged as a rising star of the Democratic Party in this election cycle. Polls released ahead of Election Day indicated that the Democrat had a slim lead over Republican Ken Paxton in the race to represent Texas in the U.S. Senate. He ended up defeating Paxton by about 12 percentage points, breaking a nearly four-decade-long streak of the state sending a Republican to the upper chamber.But the Senate race was far from the only victory for Democrats in the Lone Star State. In a stunning political upset, Gina Hinojosa unseated Republican incumbent Gov. Greg Abbott, who has held the office for more than a decade. His loss came as a surprise to many political experts, who thought heading into Tuesday that the probability of Hinojosa emerging victorious in the race was relatively low, though polling suggested that this fight was more competitive than Abbott’s past re-election bids. And the blue wave swept over other state races too; Democrats won the majority in the Texas state House, bringing an end to more than two decades of Republican control in the chamber, as well as scoring victories in every statewide contest on the ballot this year and flipping multiple U.S. House seats to boot.Kirby Goidel, a professor of political science at Texas A&M University, says that all this suggests that Tuesday was not just a one-off.“It wasn’t limited to a single race, it wasn’t limited to a single office—it was across the board,” Goidel says. “I don’t think it’s just a blip because of the scope and the depth of the wins.”And while Texas was the most dramatic example of Democrats’ success in a red state, others also saw races that were more competitive than many had anticipated.In South Carolina, Democrat Dr. Annie Andrews’ victory over GOP Sen. Darline Graham “was the beacon,” says Shannon Bridgmon, a political scientist at the University of South Carolina. But Bridgmon says that there are other contests that are also notable in the state. In the race to represent South Carolina's 1st District in the U.S. House—to succeed GOP Rep. Nancy Mace—Democrat Nancy Lacore defeated her Republican opponent, Jenny Costa Honeycutt, by a 1.1-point-margin. Another race, for the 2nd District, has not yet been called by The Associated Press, but is extremely tight, with the Republican incumbent ahead by 1% as of Sunday evening. In the state legislature, Democrats broke Republicans' supermajority in the South Carolina House.“These numbers are much more competitive than people had expected,” Bridgmon says, though she acknowledges, “I’m not going to say South Carolina is on the level of Texas right now because they really just blew the top off in every way.”Democrat and megachurch pastor Adam Hamilton defeated Republican incumbent Sen. Roger Marshall in Kansas for a seat in the upper chamber. And, like in South Carolina, Democrats also had some success in the Kansas state House, shattering the Republican supermajority, which has dominated the state legislature for 16 years, says Alexandra Middlewood, an associate professor and department chair of political science at Wichita State University. She adds that even with some statewide races that Republicans won, “Democrats still did significantly better in those races than they have in the past.”“Now, that is to say, there are still three members of the [U.S] House that are Republican from Kansas. All three of those incumbents maintained their seats. [Republicans] are still obviously a majority in the Kansas House,” Middlewood says. “But the fact that Democrats were able to mobilize such significant shifts to the left is a really big deal.”Political scientists attribute much of Democrats’ success in many of these races to a “perfect storm” of issues that coalesced in this year’s election cycle. Much of it, they say, is because of anger at the Republican Party and Trump over the Administration’s handling of the economy and affordability issues, as well as the Iran war and his immigration crackdown. Costas Panagopoulos, a professor of political science at Northeastern University, says that, in addition to frustration with national Republican leaders, the specific candidates on the ballot likely also played a role in some of these races. Paxton, for instance, was widely viewed as a weak candidate for Republicans in the Texas Senate race; his campaign was bogged down by past controversies, including infidelity allegations and an impeachment trial (he was ultimately acquitted of all the charges he was facing), among others.There were also atypical circumstances in some of these races. In South Carolina, for instance, Bridgmon says that the late Sen. Lindsey Graham’s death fundamentally changed the Senate race. Before his unexpected death in July, the late Senator was widely expected to be re-elected in this year’s midterms.At the same time, there are long-term dynamics that have been brewing in many of these states that played into what happened on Election Day, according to Panagopoulos. For instance, “the South has experienced tremendous population growth” in recent years, he says, which in turn has led to many of those states becoming more diverse and is having “ripple effects” on their elections.Goidel says that “there were lots of pieces that were falling into place” this year.“I think all the conditions came together at the right moment for this to manifest itself in this particular cycle,” Goidel says. “There are differences across states and how deep it went and whether it was one race or multiple races, but what we definitely saw is a move away from the Republican Party—that’s the way I would express it, less a movement to the Democratic Party, more a movement away from the Republican Party—because voters are frustrated and they’re mad and it’s very clear who’s responsible.”“People are mad at Trump for different reasons,” he continues. “And whether that all coalesces and stays the same going forward is not clear to me. And how the parties respond going forward is also not clear to me.”Are these deep-red states becoming more competitive?Democrats clearly gained ground this midterm cycle in these states that historically have not really been on the board for them, but political scientists say that whether they can maintain that momentum in future elections remains to be seen.Middlewood says much of this depends on what Democrats do once they’re sworn into office in January and take control of Congress. If Democrats pass laws to address the affordability crisis, make moves to improve healthcare access, and take steps to address other issues that voters care about—for instance, ethics and anti-corruption—then “they will continue to get votes here in Kansas,” Middlewood says. Otherwise, she says, they will likely “lose some of these voters that shifted to the left.”“I think that Democrats, even in Kansas, have a really good opportunity that, if they are strategic, they can hold onto these voters,” she says. “I think the best way that I’ve heard it be put is that these voters are ‘on loan’; they are not reliably Democrat … and that the Democratic Party really needs to prove themselves to these voters. And I think that’s true everywhere, but I think that’s especially true here in Kansas because these are reliably red Republicans, in general.”She says she also thinks what happens going forward will depend on how the Republican Party responds to these results, and what it will look like “post-Trump.”“Do they do this total autopsy and reset, where they find themselves a new platform and they move forward and they acknowledge that he is the reason for this huge backlash election—his policies in particular? Or do they continue down the Trump road?” she says. “Because I think a big part of this election—nationally and certainly in Kansas—is not even that people now have more affinity for the Democratic Party; it’s that people were unhappy with the status quo, and the Democrats were the only alternative.”Similarly, Goidel says that, despite the blue wave on Tuesday, he doesn’t think Texas is itself a blue state now—but it’s certainly becoming a more competitive one than it has been in the past.“I would be surprised … if we go back to a period of just conservative domination of the state and that we just say ‘Texas is a red state, Democrats can’t compete,’” he says. “I think now, we’re in a place where Democrats should be able to compete going forward.”Goidel points out, though, that the Republican Party is still very much present in Texas—and that it will likely be making some changes in the aftermath of its devastating losses on Tuesday. That said, so will Democrats, who will likely be recruiting and funding more candidates in races that they may have previously written off, he says.Democrats’ success this year doesn’t necessarily mean they’ll have the same kind of success in Texas in 2028, Goidel says—but, as the next presidential election approaches, he says he thinks that Texas will be a state on both parties’ minds.“I think both parties are going to believe that Texas is in play in 2028,” he says.The midterm results don’t mean that South Carolina is becoming a blue state like Massachusetts, Bridgmon says; the state is still conservative. And what happens in 2028 will depend on what both parties do next.“There are other elections out there that were not supposed to be realigning or transitional elections that turned out to be, but we didn’t know it until later,” Bridgmon says. “It remains to be seen if this will too, but we’ve got an open presidential race in two years, and so the ground is ready for new political ideas and movements.”Panagopoulos says he thinks this year’s midterm “was finally a moment in American politics when voters were clearly willing to put their policy interests ahead of any partisan considerations and hope that that produces better outcomes for them.” Whether that will continue into future elections is not yet clear, and he echoes other political scientists’ thoughts that much of this hinges on how both parties respond to the messages that voters are sending them. But he thinks it’s certainly possible that Democrats’ momentum in red states could continue into 2028.“I don’t think either of the major parties can take any state for granted because any red state can become a blue state, and frankly, any blue state can become a red state under the right circumstances,” Panagopoulos says. “Many places are somewhere in between red and blue and they are competitive; perhaps more competitive than people have realized.”“It’s possible that this Democratic blue tsunami we experienced in 2026 may foreshadow even greater Democratic growth in 2028, depending on what happens over the next two years,” he continues. “In many ways, it’s hard to predict what’s going to happen.”
