either...the GOP was happy to have "Tricky Dick" serve out his second, and final, term...it wasn't until Mr. Dean mused that he thought Nixon might be recording a conversation he had with RN, that the wheels started turning and someone investigated that notion...enter Mr. Butterfield and the 'Nixon Tapes'...the Saturday Night Massacre... and finally Barry Goldwater telling Nixon that there were 11 Senators who would still support him...but Goldwater wasn't one of them...end of story.
Now, to today...
Every economy in the world is suffering, thanks to Vladimir Putin's insanity...the Biden administration is working very hard to lessen the impact of this war..."Biden Corruption" is no more than a baseless meme by his opponents...as is his "dementia"...btw, I've seen him put thoughts together much better than what you post here ;-).
I will grant you that the 'Mainstream GOP' leadership (McConnell, Romney, etc.) do want all traces of Trump erased...but that's going to be problematic given the essential block of voters he controls. For 'Middle of the Roaders' these hearings aren't helpful to the GOP, and IMO any Presidential candidate in 2024 who doesn't distance him or her self from Trump with a 10x pole will have some serious headwind.
