I am not in the tinfoil hat brigade but I'm guessing that Trump's actions didn't move the needle one bit for any undecided or fence-sitting voter.
To the extent I care about Bill's accusers and their relationship to Hillary, I care a hell of a lot more about plans for the economy, foreign policy especially wrt the Middle East and Russia, ideas for Obamacare because you can't just pull the plug on it in a day, etc. Trump made issue #78 the talk of the day, like the moron he is.
