Re: Well this seems to tick ALL the boxes
The point of impeaching Trump is political theater.
No one in the House dreamed for a second that the Senate would convict. (That would have been disastrous for the Democrats.) They impeached suspecting that McConnell wouldn't be able to resist putting on a blatant show trial, because McConnell can't resist throwing his weight around here at the very peak of his power. And they counted on that to "energize the base", to use a favorite cliche of the party machinery.
McConnell is probably hoping for the same effect, because he knows he's putting some vulnerable Republican senators at risk. But ultimately I suspect he doesn't care. He's king of the hill at the moment and his only real pleasure is pushing other people down. He has no policy agenda of his own (he's a champion flip-flopper, having once fillibustered his own bill); all indications are that he's only interested in power for the sake of power, and his route to it has been obstruction, so obstruct he will.
Basically, the point of impeaching Trump was to highlight McConnell again for the professional bully that he is, in the hope of increasing Democrat turnout in November, and maybe irritating some of the former anyone-but-Trump Republican voters into staying home.
Will it work? Hell, we'll probably never really know. But Democrats control the House and they had to be seen as doing something other than papering McConnell's desk with bills that will never get a hearing.
