Go ask the Democrats. I'm not being flippant, but they're the ones who act like it's an embarrassment (kind of like the way the Republicans reacted when Barr was pushing for impeachment based on the corruption of the Clinton administration - prior to the Monica scandal).
There are days I think just swapping poor Pence
for DJT is not a bright idea. I agree. Things like
this ought not to happen for frivolous reasons. I
know why Nixon picks Agnew. Mike Pence has a
tendency not to independently think for himself.
Mike Pence once ratted on his close friends in college when they bought a beer keg and tried
to throw an ANIMAL HOUSE party on a shoestring budget. He tends to believe in regulations.
If the dems take the house, the leadership wont allow impeachment unless Trump actually does something big like perjure himself or evidence of obstruction or whatever.
