Dem civil war: The battle for their future in the Trump era
Moderate candidates led Democrats to two unlikely special election victories: first Doug Jones in the Alabama Senate race, and now Conor Lamb in a Pennsylvania House race. At the same time, the progressive wing of the party is energized by Trump's election and even attacking fellow Democrats who they consider to be too moderate.
Why it matters: There's always tension in both parties between those at the center and those on the more extreme ends of the political spectrum. But this year there's more at stake for the Democrats, who are trying to retake the House of Representatives while navigating this ideological war.
