Liz Cheney almost certainly loses her primary. It's more a question of which opponent beats her.
Matt Gaetz, if he doesn't resign first. I do question just how long ambitious local Republicans will stand by him, especially if they smell blood in the water.
Adam Kinzinger. Like Liz Cheney, it's a question of which opponent beats him (assuming Kinzinger doesn't run for Governor or Senate).
Steny Hoyer and Jim Clyburn might be vulnerable to challenges from the left (I'd put Pelosi in this category too, but California doesn't have traditional primaries)
Jake Auchinloss almost certainly will face a serious primary challenge, and he might well lose.
Closer to home for me, Carolyn Maloney and Hakeem Jeffries could also face challenges from the left as well.
I think Jeffries is safe. He seems pretty active in the community and the desire to primary him mostly seems driven by a personal conflict. He's also a lot younger than most of the targets of the JD and is seen as a potential future speaker.
Maloney could be vulnerable - old, weird, and sort of centrist - but I don't see her losing to her latest challenger unless her district is heavily redrawn.
