The response, one would think, is rather simple.
Demand the accusers sign a legal affidavit and file a police report combined with civil lawsuits against any false accusations.
How many accusers would come forward if the had to sign legal documents attesting to their claims ?
This is why it's actually better to run a candidate like Donald Trump or Kid Rock who has spent years in the entertainment business and in the gossip pages of newspapers. People except this type of personality to be a little off, so accusations of most forms of misbehavior are easily brushed off.
If we're going to be governed by a bunch of crooked deviants, why not run candidates who are at least fun to watch on the campaign trail?
Plenty. Since it's impossible to disprove most of these 'he said, she said' crap, no legal document concerning it could have any force.
I’m not versed in the law, but this sounds like a good antidote.
