The latest Mason-Dixon poll shows Nevada Republican Senate candidate Sharron Angle regaining ground she had lost to Sen. Harry Reid (D.). The two are now neck-and-neck:

“This race is always going to be close,” said Jennifer Duffy of the Cook Political Report, which judges the contest a toss-up.
“It’s a tough race for Reid, and it’s also a tough race for Angle. Ultimately, if she wins, it means the race isn’t about her; it’s about the party in power.”
The new survey by Mason-Dixon Polling & Research shows Reid and Angle neck and neck. The Senate majority leader would win 43 percent and Angle 42 percent of support from likely Nevada voters if the election were held now. The margin of error is plus or minus 4 percentage points on the statewide telephone survey of 625 registered voters taken Monday through Wednesday.
