The Senate campaign of Republican Richard Burr is surging in North Carolina. Last month, most polls showed him trailing Democrat Erskine Bowles by 8 to 10 points. Many Republicans criticized his tendency to micromanage his campaign (he likes to drive himself to his events) and praised Bowles as a vastly improved candidate compared to his losing performance against Elizabeth Dole two years ago. Both of these observations remain on target, but they haven’t prevented Burr from pulling even with Bowles. In fact, I’ve seen a few polls–including a brand-new one from Survey USA–showing Burr ahead, 47 percent to 45 percent. This race has gone from one Republicans felt pessimistic about a few weeks ago to one they’re hopeful about today.
