October surprise. If Hillary looks like a loser they will play the “health” card and parachute Biden, who will be able to discard all of the Clinton email/Foundation scandal and present as Mr. Clean. Trump wouldn’t have the resources or time to push a new narrative against Biden.
The fact that we all acknowledge a Biden parachute would likely work demonstrates why Trump is at this point still likely to lose. Democrat voters aren’t stupid — Hillary’s personal foibles don’t matter to them and SHOULDN’T. Hillary’s ability to promulgate the executive orders and appoint the judges and file the lawsuits and sign the bills they want isn’t affected by her email discipline, her Clinton Foundation bias, her laxity in Benghazi, her ability to stand or climb stairs, etc.
