It may be that Pelosi just wants a vote to impeach in the House thinking this will damage Trump enough to cause him to lose in 2020, and assuming that the media will sway the public into thinking what the Democrats are doing is legitimate. If she can lure a couple of anti-Trump Republicans in the House to vote with the Democrats they can pretend it is bipartisan.
Pelosi isn’t that smart or forward-thinking, she kept trying to tell the young-uns in the party to shut up about impeachment, it’s a loser and will only hurt them (you know things are screwed-up when Pelosi is the voice of reason). I really get the feeling that she’s along for the ride on this one, somebody got something on her or got her to sign a document while high on pills or something.
And what a sackless bunch of Republicans we have. They’re such losers that they have no idea how to act when they have the majority and all the advantages. They’re still walking around with their heads down like the lame-duck party they were 3 years ago. Pathetic.
