I don't know that we're ever going to have a successful impeachment and conviction, even if our republic were to last another 2 centuries. The Clinton impeachment was a weak and partisan show that never had a serious chance of succeeding. Nixon didn't have to be impeached because, after enough damning Watergate evidence came out, Goldwater and a respected house Pub went to Nixon and told him he didn't have the votes and needed to resign. You just can't successfully impeach and convict solely on party lines. You need erosion of Pub support in congress so that it is bipartisan. In order to get that, you need erosion of Trump support among Pub voters. And we're not there yet. May never get there.
The other thing is the timing. Ph is right. This impeachment and trial would be at least several months because there is a mountain of evidence to sift through, compared to the rather easy case of Bubba lying about a blow job. And you probably can't do that in an election year from a practical political perspective, which means you'd probably have to begin such proceedings by sometime this summer. And we don't have the whole Mueller report yet - we just have a few leaks and info from some investigative reporting. We don't do a damn thing till Muller releases his report.
And for those who want to impeach right away, here's our worst nightmare. Let's say you do impeach. The senate then acquits Trump on all charges. Then you want to prosecute him criminally after his presidency. That acquittal in the senate will go a long way toward establishing reasonable doubt in the minds of 12 of our not the sharpest tools in the shed. That's assuming double jeopardy hasn't attached to begin with. (I'm guessing an impeachment and trial and the senate wouldn't count as a 1st trial for double jeopardy purposes, but I'm not positive.) And it's not like we can try and execute him like Khrushchev did to Beria, so let's be patient.
Look, I get we're all frustrated, and y'all want your pound of flesh. But I'd rather not engage in a political stunt that is bound for failure when that might hurt a prosecutor's chance of getting a conviction at some point later - or sooner if it is determined that criminal charges can be brought against a sitting president. And all we have right now, in terms of enough evidence to convict, is evidence of obstruction of justice. But what Mueller may still be sitting on could go a whole lot further than that. I'm thinking money laundering, income tax evasion, conspiring with a hostile foreign power to influence an election, being an agent of a foreign power without registering as such - you know, some potentially treasonous stuff. I could give a shite about a pee pee tape or even obstruction, which is what Bubba was impeached on. If Trump has been engaged in more serious crimes, I want him in jail for the rest of his life - sorry abolitionists. But that ain't happening from a partisan impeachment.
