Rasmussen Reports has North Carolina’s U.S. Senate race between Richard Burr and Elaine Marshall tied.

A poll from before the June 22 runoff between Marshall and Cal Cunningham gave Burr a comfortable lead over both opponents. Marshall is enjoying a post-runoff bounce, Rasmussen says:

The latest Rasmussen Reports statewide telephone survey of Likely Voters shows Burr picking up 44% support while Marshall picks up 43%. Seven percent (7%) of voters would choose some other candidate and six percent (6%) are undecided.

These results mark the highest level of support for Marshall and the lowest support measured for Burr in surveys going back to February. Prior to the latest poll, Burr?s support ranged from 48% to 51%, while Marshall?s support fell in a 32% to 40% range.

Earlier this month, Burr held a 50% to 36% edge over Marshall.
