Wow, all of them are conservative districts.
Well obviously. Any Republican-held district that is in any way not "conservative" is going to be on the first list. Unless you're referring to a specific type of conservatism?
Anyway, I like this list, although I wish AK-AL, UT-04, and OH-16 were on there (I'm probably forgetting a few). Also MT-AL but that's a special case since it could have a Democratic incumbent (and if Gianforte wins, their decision will have to depend on his margin on Thursday). Good mix of rural and suburban districts.
