It’s not just that, it’s that Trump is leading by large margins almost everywhere!
If Trump had ONLY been polling well in the 4 states that have actually voted, and was polling poorly everywhere else... THAT would be a completely different matter.
There is ZERO path to the nomination anymore for Rubio and Cruz and everyone else should have already dropped out by now.
But, but wait, Rove and the other “real conservatives” said Trump peaked and has hit his ceiling, so how can his numbers be higher, he’s declining they said it. Lol
Trump is an undisciplined jerk, and he may yet turn enough people off. I will likely vote for Rubio.
