A new Public Opinion Strategies (R) poll in Nevada shows Sen. Dean Heller (R-NV) leading Rep. Shelley Berkley (D-NV) in the U.S. Senate race by six points, 48% to 42%.
Jon Ralston notes that while pollster Glen Bolger works for Republicans his work "generally has been spot-on in Nevada -- for example, he had Harry Reid ahead of Sharron Angle by 5 percentage points late in the 2010 Senate race, just off the final margin."
