Obama is the clueless President anointed by the media elite. He is quite stupid and was never fit for office. He never accomplished anything of note and has made a giant mess of the USA.
Obama thinks it is his job to lecture the citizens how to vote on the EU. That is an internal matter best left to the citizens of the U.K. . One can argue they are better suited to make decisions about their future than a country that elected the clueless one twice.
