Stanton fends off progressive House challenger in Arizona Democratic primary

Greg Stanton just beat back a primary challenger who ran to his left on the Laken Riley vote, and it wasn't close. That tells you something worth sitting with for a minute. Kai Newkirk built his whole campaign around punishing Stanton for backing a bill that mandates detention for illegal immigrants charged with certain crimes, a bill so obviously reasonable that even plenty of Democrats couldn't vote against it without fear of getting buried. Arizona voters, including plenty in a competitive district, said no thanks to the purity test.

This is the same pattern we keep seeing when progressive activists try to drag safe-seat Democrats further left on immigration or crime. The activist class treats the Laken Riley Act like a betrayal. Actual voters, the ones who live near the border and watch local news, treat it like common sense. Stanton read the room. Newkirk didn't, and he also went after Stanton for taking corporate money, a line of attack that plays great on a podcast and terribly at the ballot box in a district that isn't exactly Berkeley.

None of this makes Stanton some closet conservative. He's still a reliable vote for his party's agenda on most everything else. But the fact that this particular vote, on this particular issue, is what his own base tried and failed to nuke him over says the politics of immigration have shifted more than Democratic strategists in DC want to admit. Even in a blue district, running to the left of "detain people charged with violent crimes after entering illegally" turned out to be a losing message.

Republicans shouldn't get smug about this one. It's a primary, not a referendum on the whole party. But it's one more data point suggesting the fringe demanding total resistance on immigration is louder online than it is with actual voters, even Democratic ones.
