I remind you that Trump didnt win more than 50% anywhere until the bandwagon effect began to take effect. In NY State Trump only got two/thirds as many votes in his primary as Bernie did in his and and Hillary got twice as much.
I remind you Trump received a higher percent of the vote in Florida than Cruz did in his HOME STATE. And of course Trump wiped the floor with a sitting Senator favorite son in FL.
He did not win over 50%. What Trump realized was that the primary system was rigged to favor the front runner and he managed after Iowa to stay ahead of a big field. As for Florida, Trump owed this victory to the feud between the Bushies and Rubio. Jeb should have dropped out after NH. but his backers had took much invested him.
The one thing I have never understood was that first debate run by Fox. Blondes very first question was do totally out of line. Did they know him, did they know his audience so little that they thought that this would take him out?
