Couldn't be simpler.
One man. One vote. One time.
You have repeated this nonsense scores of times but even you know there is no logic to it.
Romney has spent five years and piles of money securing the GOP nomination. It is all but in his hands.
Why would Romney suddenly now decide to simply not accept that which he has earned?
And if he did, who will decide who the nominee is to be, and which three people are among the top candidates at this point in time?
Your whole line ignores reality and defies reason.
