Dean Heller’s campaign has released a survey done by the Terrance Group that shows Heller with a 22 point lead over his primary challenger Danny Tarkanian. Heller campaign spokesman Tommy Ferraro says Tarkanian is on track to lose his 6th race for office, adding “Voters have rejected him time and time again and this race will be no different.” Sarah Palin has endorsed Tarkanian in the primary.
