“Yet, the GOPe meme continues to be We must pick a different nominee, because Trump a majority of voters are voting against him!” “
The other thing I’ve seen is that Trump is the number 2 choice for at least half of the people that voted for other candidates.
I doubt Jeb Bush was the number two choice for many voters.
Fallacious argument there. The important question is, to whom would Rubio and Kasich supporters go if they drop out. The fact that 60% are not currently voting for Trump and 80% are not voting for Cruz has absolutely nothing to do with who those voters would vote for, with Rubio and Kasich out of the race. I believe recent polling has shown the vast majority would go to Cruz, not Trump. I do believe there is indeed a Trump “ceiling” of around 40 to 45%. The only way we will know is if Rubio and Kasich are out.
