Say what?

Rassmussen, which always seems to skew a bit GOPish anyway, has Richard Burr with a 56 percent job approval rating. I’m not sure I’ve seen many politicians crack that for reals in NC in quite a while, let alone a one term incumbent Senator.
They’re also calling the Burr-Marshall race at 52-37.
The poll is based on likely voters, which could eliminate the new voters signed up during the presidential race depending on the criteria.
The number I’d really like to see is name recognition.
How many people really know who their Senators are?
