^Perdue losing is pretty unlikely IMO (because of the runoff law). He is no Isakson, but he knows his state is changing. Maine only flips if Collins retires.
I get the impression that Perdue isn't all that well-liked, but I see your point. And to answer someone else in the thread - I'd put money on Ernst winning re-election by at least 5, if not by double digits. Alaska is an interesting prospect - but only if in the very unlikely event that Dan Sullivan retires.
Ernst strikes me as a very weak incumbent, tbh.
