The Senate race may be tightening.
According to a recent survey by Research 2000 for the liberal Web site the Daily Kos, U.S. Sen. Elizabeth Dole had 50 percent support, while Democratic rival Kay Hagan had 42 percent.
Eight percent were undecided.
Blogger Markos Moulitsas Zûniga writes that Dole is right at the 50 percent mark "considered 'safe,'" though he doubts she can "just slack off."
The results are a little closer than other recent polls, which have generally shown Dole with a double-digit lead.
The survey of 600 likely voters was taken July 28-30. It has a margin of error of four percentage points.
