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.
How do you know WHAT my feelings were the last time? Honestly, I was never a Romney fan, and would have been fine if Santorum could have forced an open convention. You never saw me calling for everyone to get behind Romney.
