"To keep America great we have to change direction," says Wilson at the conclusion of the ad. The Wilson campaign would not comment on the size of the buy. She hits the airwaves about a month ahead of the June 5 primary. Wilson has cleared the field of any notable GOP competition, a departure from the bloody 2008 Senate Republican primary, in which Wilson was defeated by Rep. Steve Pearce. Wilson's strong standing in advance of the primary has allowed her to conserve money and try to build positive name ID ahead of the general election. Given how unpopular Congress is, it's no surprise she omitted the resume line from her first ad. Rep. Martin Heinrich is the frontrunner in the Democratic race. He is expected to get by state Auditor Hector Balderas in June. Heinrich's first TV ad, launched last week, also did not contain any prominent references to his congressional career.
