Sorry, Trump is going to have to win the nomination the old-fashioned way - by winning the most delegates. If he can’t, that is on him - not on the people that won’t just get in line when he says so...
I'll tell you why, it's because the GOPe weren't conspiring against Romney, they were conspiring for him, and to force a second ballot would only delay the inevitable. In Trump's case, to force a second ballot, and third and so on, until they get their way and select Ryan as the "consensus" nominee, will make so many people so angry that the Dem nominee will be guaranteed of victory.
So, you want to allow a loser to stay in the race to play spoiler for Trump when you wouldn't suggest that for Romney. You are supporting the establishment AND Hillary at the same time. Congrats. Amend your nickname, unless you want it to be ironic.
