Two new polls have incumbent Sen. Dean Heller (R-NV) pulling away from embattled Rep. Shelley Berkeley (D-NV) in their Senate race. According to a poll from SurveyUSA, Heller leads 46-40; according to Rasmussen, Heller leads 50-43. The margin of the lead, of course, is approximately the same in the two polls. Berkeley’s campaign has cratered over the past several months; the implosion began with revelations reported at Breitbart News about her corrupt attempts to direct money to her husband’s nephrology center.
