Someone at Political Wire declares that Richard Burr (R-NC) is comfortably ahead of all potential challengers, because he has 43% of the voter against all of the, 43%-31% against Elaine Marshall, 43%-28% vs Cal Cunningham, and 43%-27% against Kenneth Lewis.

Just so you know, the rule of thumb is that undecideds break at least 2:1 against the incumbent,^* so any time an incumbent is below 50%, they are in trouble, and an incumbent at 43%, is is very real trouble, particularly when his approval number is 38%.

This number has his campaign staff soiling their drawers.

Morons.

^*I ran the numbers against Elaine Marshall and it comes to a 3% margin in the best case.
