His ignorance has been on display for so long the public hardly takes notice.
IMHO the biggest reason the masses hardly take notice is because the socialist government controlled so called main stream media totally refuses to report any thing negative about Obama! They only report negative stories about Conservatives, even if they have to fabricate a story. Like Conservative war on women.
No doubt about it. If the press were even halfway honest he never would have made it to the runoff stage against Hillary Clinton.
