If it were a shill, he'd be younger and acting over the top.
This one video doesn't cancel out the hundreds of videos and signs of real racism by tea party members.
The tea party is and has always been a hodgepodge of libertarian, far-right, anti-government, fringe, racist, and homophobes...
IMO on some level the majority of the tea party doesn't like having a black president... Many may not even be conscious of the this, their racism so deep seeded, but their hyper-partisan talking points reveal an hollow anger masking something else.
