Apparently, that was a deciding factor in Dean Heller declining to challenge Harry Reid next year. He knew "The Ensign Effect" was dragging his poll numbers down and keeping the overall GOP image down. He obviously knows he's better off trying to knock off Johnny Casino himself in the 2012 primary than trying to go against Nevada's most powerful voice in Washington.
Well, that's OK. Let Heller sit it out. Johnny Casino can pull someone else down next year before he loses his own seat in 2012. Aren't the Nevada Republicans so lucky? ;-)
