Apparently his opponent has recieved upward of $50,000 in contributions since the incident.
A tally that will not be sustained, through November 2010 (by which point, this event will be long-forgotten), and a sum that will likely be spent well before then.
I think Wilson acted like a jackass, who deserves to be voted out, but the political reality is that this won't be what convinces his constituents to do so. All this event has done is momentarily galvanized those on the political extremes, and in his district, there are a lot more people on his extreme than on the opposite.
