Former state Rep. Amish Shah won the crowded Democratic primary for Arizona’s 1st District on Wednesday, defeating an establishment pick and other well-funded candidates for the battleground seat.

The district, which President Donald Trump carried by just three points in 2024, is one of Democrats’ top pickup opportunities this cycle — and the tight primary evolved into a test of party leaders, after the Democratic Congressional Campaign Committee backed former broadcast journalist Marlene Galán-Woods.

In the end, voters rejected Galán-Woods, the latest example of an establishment-backed candidate losing as Democrats continue to show frustration with leaders in Washington.

This year marks the second consecutive time Shah won the district’s Democratic primary: He won it in 2024, before losing to Rep. David Schweikert (R-Ariz.) by four points in the general election.
