He’s the first one to truly hate America. Even Carter and Clinton (as much as I hate to admit it) don’t hate America. Carter’s policies were (and his current thinking is) the functional equivalent of hatred of America, but I don’t think he actually feels the emotion. Obama feels the emotion... and lives it. And Clinton was (and is) just the most corrupt person in American History, nothing in his thinking is deep enough to qualify for hatred of America.
I believe that Carter did not hate America until he left office.
