Mark Hutchison's campaign for Nevada lieutenant governor is taking on Republican primary opponent Sue Lowden for donating to Harry Reid in previous elections.
The 60-second radio ad released Thursday says Lowden contributed five times to the Democratic majority leader's campaign.
Hutchison is midway through his first term as a Nevada state senator. He has the backing of Gov. Brian Sandoval, a fellow Republican.
Lowden is a casino owner and former state senator who ran unsuccessfully in the 2010 GOP primary for U.S. Senate. She lost to Sharron Angle. Angle was then defeated by Reid in the general election.
The lieutenant governor's race could be pivotal in Nevada politics if Sandoval decides to seek federal office in 2016. The lieutenant governor would then ascend to the governor's office.
