Trump has pulled the masks off of many.
I'm no fan of Trump (just in case I hadn't made it abundantly clear), but to his credit he has won his victories fairly and above board. If all trends hold he'll hit the 1,237 threshold. By all means, let all the remaining states have their say... but this bullsh*t talk of screwing him over at the convention and/or running a third-party is destructive.
The task of defeating Her Infernal Malevolence in November is going to be daunting enough without meddling GOPe sore losers f***ing up the effort yet more.
