Eviscerate Anderson Cooper in spectacular fashion in front of 25 million people during the next debate and small details like this are quickly forgotten. 
yep. Trump is the king of "ATTACK THE MESSENGER".
Trump can be completely wrong in an argument, completely owned with details of his own political position hypocrisy, completely unable to explain any of his positions, and will still emerge with his "base" cheering him on, as long as he makes it personal and delivers a nice feud for the sheeple to cheer.
Trump is an entertainer, exploiting the anger and ignorance of the politically idiotic. Any time a person "likes some of his ideas", well, they are either stupid (trump is #1 on border, BUT he also supports amnesty for 11 million) or uninformed.
But it's america. People can be stupid. Trump will lose 40 states as the nominee. But you have to remember, the people that love him also believed, and I mean truly believed, that Palin "knew more about energy than anyone else in the united states", as mccain put it. They believed cain never cheated. They just want heroes, something about their own role models molesting them, one can only assume.
