I'm not so sure it would be futile.
I know the dems are somewhat apprehensive of impeachment. When the reps impeached Clinton, it only made him stronger. I don't see that happening in this case.
With Clinton, they impeached him over a land deal that he had lost money on ten years prior. Then they tried to drag Hillary in it and could find no wrongdoing on her part also. They finally had to settle on lying about a personal extra-marital affair, something almost half the nations adults have participated in at one or more times in their lives. All this while the guy pushing this, Newt Gingrich, is found out to be getting blow jobs from his mistress in the senate garage. It made the Clintons quite sympathetic figures.
I don't think that will happen with Trump. This would put his extremely shady past front and center for all to see and Fox News would be hard pressed to cover it up as they've been doing so in the past. All his mob ties, his dirty real estate deals, bribery, corruption. All the things that have been his stock in trade his entire life will be exposed on National TV. He will certainly not become a sympathetic figure. And they will still have the presidency of Pence, lame duck though he will surely be.
Republicans will have to decide what is more important to them. The Trump presidency or retaining some sort of political power after 2020. If they choose Trump, they are choosing the trash bin of history for themselves.
I agree. The spectacle of putting the shitgibbon on the stand, under oath, and assuming the dems could get some real hardball questions and really grill him, would probably be enough to undo his popularity even among a lot of his 'base' (not all of them, but there's naught to be done about them, really). Every time he answers "I don't remember", follow up with one of the many clips of him saying he has the 'best memory'. Every time he says anything, play a clip of him saying the opposite (really, it wouldn't be that hard, they could hire the Daily Show guys to do it for them on the fly) and ask if he was lying then, or lying now. He would lose it in under an hour, guaranteed.
I think it would trivial to actually impeach based on what is in Mueller report alone, but that's not all there is.
When the senate votes, even if they do not convict, make them own it. Find every single quote by a republican about what (Bill) Clinton did and how they voted then. Find every quote by the GOP that says how bad they think trump is, and then ask why they didn't convict. Just keep hammering on that through the election and make them fucking own it.
We know it won't affect a significant chunk of the base, but fuck those deplorables, it's the rest of the country that matters.
