On board generally there, but, some things:
1) You are CORRECT that Biden has been the most successful President legislatively in a generation. It is actually AMAZING what he has gotten done. Wasn't expected or required of me to continue to support him...I only needed that he beat Trump. The HILARIOUS thing about it is he got some of it done because TRUMP lost the House and the Senate for Republicans! Ha! We got some more gun control which is a good thing. He got some climate change legislation passed (good to control pollution regardless of whether you believe it affects climate change). He got more necessary help for veterans. Republicans talk a good game about supporting our troops, but what they support is the War Machine, not the actual troops. Biden got it done there. Infrastructure, chip manufacturing, extended Affordable Care Act, and on.
2) I wouldn't call his approval rating "soaring." It is trending upward from where it was, but "soaring" is more than a bit much...just trying to be realistic here, not contrarian.
3) Knock on wood regarding the Senate. I BELIEVE Democrats will keep the Senate. McConnell appears to know that, but midterm elections are always an uphill battle for the party in power, so this is not a guarantee or even close to one.
4) You are CORRECT that Trump lost the WH, the House, and very actively lost the Senate (so comically actively). The fact that they still stand by (and worship) a guy who was such a loser that it extended beyond himself shows how stupid they are. More than past time to move on, but they are in a cult. This was really the only thing I was wrong about (well, I missed Florida) regarding the 2020 election. I had wrongly assumed that Trump would quickly become yesterday's news after losing. It is happening, but it is WAAAAAAY slower than I thought it would be, so there I was wrong, and for that I apologize unreservedly. Never having been in a cult myself, I can not wrap my brain around the pull that a cult has to a cultist's mind.
As an aside, Trumpers are out of their freakin' minds. And the election deniers need deep therapy and probably medication and maybe even fuzzy slippers and jello with every meal.
