Meanwhile, in the 2010 Senate race

Cal Cunningham has a golden retriever named Davidson. That, and other fun facts about the potential Senate candidate at his rather extensive Wikipedia page. Roll Call says he's thinking seriously about it. Politico says Insider Advantage poll "finds Burr with just a 39 percent approval rating, with 31 percent of North Carolina voters disapproving of his performance." We're in an era in which incumbency is no where near the advantage it once was. Looks like a wide open race.
