If we were to have a serious converation regarding this whole affair, the tenor here would be somewhat different.
First, it's clear that the democrats intend to so damage Trump that his re-election would be unthinkable. Impeachment hasn't been the goal, but it looks like the democrats will impeach. It does matter, but it's just as likely to backfire, as not.
Second, Schiff's hearings and the lack of due process are troubling, and should be to all objective citizens. Naturally, due process was never a consideration in Schiff's estimation, but rather how to avoid any real tip of the hat to such things through a hearings theater.
Third, Yovanovitch was a credible witness. Hardship postings are, well, hard. I've done them. That doesn't alter the result of Jordan's questions, which clearly demonstrate a partisan element to Yovanovitch's actions, or lack of action, in Ukraine vis a vis the 2016 elections. That, in and of itself, us why I question Yovanovitch's claims of an anti-corruption effort. It's a nice talk, and as talks go, she could do worse. But there's little concrete action or result to back that up.
Finally, Yovanovitch was only credible within that which she addressed - not to the points Schiff claimed he intended to demonstrate. Naturally, Schiff is fishing. He has nothing concrete. That was amply demonstated when Yovanovitch could not testify to any illegal acts by Trump. For those of ypu wondering if you'll survive Trump, you should probably also be asking yourself if you'll survive Schiff.
