I would imagine that Obama would be well informed by his PR team and WH staffers about just how (un)popular he is right now and what to expect from disgruntled Americans along the way.I'm sure there's a "what to do in an emergency" leaflet lying around the bus somewhere for occasions just like that.This particular incident involving Ryan Rhodes stems from an incident at the height of the debt ceiling debate when Mike Doyle allegedly referred to the Tea Party members as "terrorists".
