It's only "mind-boggling" to those that haven't been paying attention, or haven't been to a Trump Rally.
He has been doing this all around the country for months now, he had 15,000 in the arena in Mississippi on 1/2/16 with another 5,000 in the overflow crowd for the simulcast in the convention center next door. Same thing at the rally in Sarasota that we attended on the Saturday after Thanksgiving, building at max capacity with a few thousand overflow waiting for him outside to speak after he was done inside.
People started lining up at
10AM yesterday in the sub-freezing temps for a
7PM rally. Saw a poll on TV this morning that showed that Trump far and away leads with supporter commitment (84% combining "Definitely Supporting" and "High Probability of Supporting").
It all sort of puts some perspective on the isolated voices stamping their rhetorical feet and saying they will
never vote for him!
