Of course if Ted was winning delegates by virtue of the plurality of votes you would be singing a whole different tune, and the GOPe would probably be banking on Donald to stop Ted.
But 60% do represent the will of the Republican Party. You can delude yourself into believing that they will fall in line with Ted, much like Kasich deluded himself in believing the Republican Party was behind him, and Rubio before him. After the Republican machine managed to steal Ohio for him he soon realized he was only being used to slow down Donald Trump because his influence does not extend beyond Ohio.
Ted will learn that very same lesson as well.
But as they say it ain't over til it's over and many believe Trump will end up with the necessary delegates to win on the first vote.
However, I believe the Republicans will pull out all stops in denying Trump the nomination even with the necessary delegates.
I'm not sure what your 60% figure is, but if your referring to the Delegate count from the Primary elections, Trump will have the nomination no question with 60% of the delegates going in.
However, to think Trump might have 60% of the delegate count at the end of this is deluded thinking.
My personal view is that if Trump gets the R nomination, the press and the Democrat machine will destroy him and either Clinton, Sanders or whoever the D's eventually nominate will be our new President.
I also feel that if Trump is not nominated he will run as an Independent and do everything in his power to ensure the Republicans do not win the Presidency.
In other words, I don't hold out much hope at all for Republicans this election cycle.
