Do you honestly see the Republican controlled House voting to impeach, and even if they did, do you see Mitch McConnell's Senate doing anything about removal from office?  I don't.  They will rally around him, a few will make noises that he is overstepping or something, but in the end, won't do a thing to put a stop to him.  If the Dems can manage to win back both the House and Senate in 2018, then there is a chance.
