It doesn't matter if there is a 'smoking gun'.
Trump is already on record of bragging about bedding other men's wives and grabbing women by the crotch.
None of that matters to the Trump faithful, anymore than it mattered to Clinton's adoring morons.
There could be a sex tape tomorrow and the rabid Trump supporters will tell us 'So what? - I didn't vote for a choirboy'. They voted for someone they wanted to poke their domestic enemies in the eyes and face repeatedly, and Trump has given them that.
So nothing else matters - even if the Democrats clearly run the swamp and not a single Campaign promise is kept.
A 'smoking gun' is irrelevant to all except those who want to use it to impeach.
