(CNN) - The GOP Senate primary election in Nevada is just over a week away, and Sue Lowden, the state's former Republican party chairwoman, is taking on one of her opponents in a new ad.
The new ad, targeting former Nevada Assemblywoman Sharon Angle, cites the results of an annual survey conducted by the Las Vegas Review-Journal that named Angle "one of Nevada's worst legislators" for four years between 1999 and 2005.
The 30-second spot, out Thursday, is running statewide on broadcast and cable television, according to a Lowden campaign spokesperson. The campaign will not say how long the ad will run or how much money has been spent on it.
A new Mason-Dixon poll released Friday gives Lowden a 30 to 29 point lead over Angle, with Danny Tarkanian registering 23 percent. In a hypothetical general election match-up with incumbent Sen. Harry Reid, Lowden holds a 3-point lead. The Senate Majority leader holds a 3-point lead over Angle, according to the same poll.
