If Donald Trump is the Republican nominee for President and loses the November election, the only person he has to blame for that loss is himself. If he loses to Hillary Clinton, then he deserves to lose to Hillary Clinton. It is not Republican voters' responsibility to automatically vote for everyone who has an "R" next to his name. It is the candidate's responsibility to convince voters he is the better candidate and then to convince those voters to actually show up and vote. If Trump does not do that, then he does not deserve to win. At least in my case, Trump has absolutely not convinced me to vote for him, and therefore he does not deserve my vote.
