US Democrats face an identity crisis at the worst possible moment

The Democratic Party is turning inward at the moment its main opponent appears most vulnerable. The article points to signs that Trump's support among the Republican base is weakening, his approval ratings have fallen to a historically poor level, and the MAGA movement is wavering.

Only two months remain before the midterm elections. Yet instead of exploiting those conditions, Trump's opponents are consumed by a long-simmering internal revolt.

The fight goes beyond the familiar argument between the party's left wing and its moderates. At stake, the article says, is a more basic question: who are the Democrats?

That identity struggle has now become the party's defining conflict, arriving at a moment when the political environment should have offered Democrats unusually favorable conditions.
