Alexandria Ocasio-Cortez has hailed a Democratic state senate seat victory in Pennsylvania as the start of the party’s comeback against the Trump administration. The win for James Malone in the 36th senatorial district–where Trump beat Kamala Harris by more than 15 points last November–was a major upset for Republicans.

Ocasio-Cortez confronted head-on the perception that she is a radical by being magnanimous toward other Democratic factions. She did not walk away from her progressive views but signaled openness to disagreement, saying her movement “is not about partisan labels or purity tests” but, rather, solidarity with the working class.

How should Democrats respond to Trump? His second term has sparked an internal reckoning.
