Rand Paul clearly has ambitions of running for the presidency, if not in 2016 then later. He got a lot of press for going to Howard University to talk about GOP outreach to the African-American community. It was not a big success, unless he was trying to get a negative reaction from the students there in order to improve his standing with the GOP base, which sees all minorities as moochers.
But even if was that was his goal, his tone-deafness and condescending attitude towards the students would have been shocking if this kind of talk and behavior had not become the norm.
The Daily Show had a good reaction.
