This is an interesting observation...I, agree to some extent...I wonder, however, if it goes a little further than that...
There definitely seems to be a restructuring going on. But I almost think it is happening in both parties.
You have the “Never Trump” Republicans that seem to be teaming up with Democrats. And then you have long time “Old School” Democrats that seem to be teaming up with Republicans. Then you have Trump, himself, who used to be a Democrat, but is now a Republican...
So, in a way, I agree with what you said. There definitely seems to be movement taking place...But I think it might be both parties that are re-evaluating their ideologies...
