Dems' Tea Party-like rebellion built by a decade of frustration

Democratic leaders are grappling with a rebellion akin to the GOP's Tea Party movement, fueled by a decade of frustration among grassroots supporters. The recent primary upsets by progressives and political outsiders highlight a growing divide between establishment Democrats and a more radical wing. This internal strife matters because it signals a potential shift in party dynamics and could impact future elections and policy directions, as disillusioned members push for more progressive agendas. The rebellion underscores a broader dissatisfaction with the party's traditional insiders.
