Apparently none of you guys watched the open hearings, or if you did you watched them on Fox and got more spin than news.
Nancy Pelosi didn't want to impeach. She fought it for a year, even after Mueller clearly laid out 10 instances of obstruction of justice (the principle charge against Bill Clinton when he was impeached) and explicitly did not exonerate Trump of anything. Trump's behavior was corrupt and impeachable, but the Dems knew that the Senate would never look at the evidence objectively.
Then we got the whistleblower's report. Then a bunch of career foreign service officers confirmed the whole report while Trump did his best to illegally prevent Congress from getting the report, then tried to block the inquiry and ordered the State Department to refuse all subpoenas for documents and his entire staff to ignore all subpoenas for testimony. The Dems will impeach because they have no choice.
Gents, the Senate will almost definitely calculate that the wrath of their base if they convict will be worse than the wrath of the rest of the electorate if they acquit. They'll decide that they can get enough misinformation out there to muddy the waters before the election. They'll probably expect Russian help again. But that won't change the facts. Trump did it, and being acquitted by a jury of his cronies is not exoneration or vindication, it's just more evidence that the Republican Party no longer gives a damn about anything but power. It will be their downfall.
