Sounds like you could have done a better job than Schiff et al, I thought they were unstructured and disorganized in their work in the House, weak and illogical in the 2 charges brought, poor in the wording, and impossibly weak in the defense of the charges in the Senate.
Yeah, I have little good to say about the majority of any of them on either side especially today. They are almost all useless, worthless, self serving unethical scum bags who put self interest above country and the constitution. I"m a tad negative about it all today. They have one last chance to at least put a bandaid on it but I don't think they will.
Given they never dreamed or seriously considered they'd get 2/3 in the senate, it's then useful to ask what the real motivations were. What were they actually trying to accomplish? I think a motive that has to be considered is that they are actually quite confused, and do not have clear motives.
But taking the alternative, if their Schiff show in total had the effect of keeping hard core voters convinced "Orange Man Bad," then that could be a motive.
All in all, I'm not comprehending what the witnesses were intended to accomplish and for what goal. They weren't going to somehow create the 2/3. So were they just to be a gambit to keep the whole show going for a couple months? Essentially more repetition of the theme "orange man bad?"
There would never be any impeachment if you assumed the other side isn't going to change their mind. As I said previously, this impeachment was far too short. There wasn't enough time for the public to really get engaged (which is where the 2/3 could come from, if we still would like to think the Senate would listen to the voters as opposed to being on their knees worshiping their King) let along all the witness/document issues. But sure, there's always a variety of motives and if you view them as the enemy it's natural to attribute everything to ulterior motives. Doesn't make it true.
The bottom line is that the "base" of the Dems have wanted Trump impeached from day one. I was impressed that they held out so long frankly. So I see things a bit differently. The only "ulterior" motive I think that has any potential validity is that it was due to one of their own, i.e. Biden, being involved. Everything else is just politics as usual.
