PHOENIX (AP) — Amish Shah won the Democratic primary Wednesday in a hotly contested congressional district in Arizona, delivering another defeat to the Democratic Congressional Campaign Committee, which backed a rival, as more voters reject the preferences of party leaders in Washington.

The DCCC backed Marlene Galán-Woods, a former Republican who switched parties at the beginning of Trump’s first term.

The DCCC’s decision to endorse Galán-Woods, a former television journalist in Phoenix, puzzled local Democrats because there was little ideological difference between her and Shah. Both are moderates, and the race was not a proxy fight in the party’s deepening feud between progressives and centrists.
