Impeachment should not even be discussed. There is no legal grounds for it.
Just let them try to impeach a Nobel Prize winner, This ain’t Burma.
They do know however, it is a specious charge which is why they don't want its possibility raised BEFORE the election because it will arouse the voters to rise up and stop this political coup. Our anger would equal and surpass dems motivation.
To your point about no grounds....1/2 of the populace knows that and will be pissed with pitchforks and maybe even guns. A key point maybe the realization from the indies that its wrong.
The pressure we put on our R congresspersons should suffice to keep every republican -- including Trump haters-- to beat back impeachment proceedings. IMHO, not many indies would go for it either, but Indies and the congress people they support could be important.
Given DjT's record I don't see Republicans losing the house. Economy, border, NoKorea....it could just as easily be a red wave....and predict it will.
