Obama knew absolutely nothing without his TelePrompTer. Could only say Uh...umm...well...um... if it blinked.
Trump, otoh, pulls out lots of info when ad-libbing, and with real humor. And Trump has military schooling and actual business success (by his own hand).
Obama is a groomed, empty suit man-child, puppet of Soros and Ayers, born of a muzzie, white-hating father and a father-hating white woman named Stanley Ann.
