Edwards gave up his Senate seat to run for veep. Burr won Edwards' seat year. There is no North Carolina Senate seat up for grabs in '06. Elizabeth Dole won the other seat in '02, so NC won't have a Senate seat in play till '08.
That's right! Forgot about that...so he thinks he's just going to breeze back into DC in four years, and pick up where he left off? Jeez, what an idiot.
