Basically each newly elected Republican lawmaker in the House and Senate has been worse than their Republican predecessor. And there's no evidence this trend is about to be stopped or reversed.
If anything the trend is about to accelerate because of all the Republicans retiring this term entirely because they're so frustrated with the intra-party feuding
we can see the rabblerousing extremists gaining momentum in real time, each opponent they drive into retirement is another empty seat that will probably elect another nutter to join their ranks
Honestly we might be seeing some of the reverse happening this cycle. Boebert, Mace, Spartz, Good, Ogles, Crane all have primary challengers who tend to be more mainstream.
