Washington (CNN) - The anti-tax Club for Growth has started a blitz of robocalls attacking Utah Sen. Bob Bennett, a three-term incumbent being challenged on his right flank by multiple Republican candidates.
"Since Utahans last sent Sen. Bob Bennett to Washington, he voted to bail out Wall Street, voted for billions in wasteful spending like Alaska's 'Bridge to Nowhere,'" the 30-second call says. "Even joined with liberals supporting big government healthcare."
A spokesman for the Club said the calls have been going out for about a week.
"Had enough?," the call asks, before telling listeners to "vote for a change" in the state's March 23 Republican precinct caucuses. Those caucuses will determine delegates to the state GOP convention, where the party's Senate nominee will be selected.
The script is the same as an anti-Bennett television ad launched by the Club last week.
Update 5:25 p.m.: When reached for comment, campaign spokesman Jim Bennett told CNN that, "Bob Bennett is leading the fight against Obamacare. This is simply more of the same dishonest nonsense from an out-of-state special interest group trying to tell Utahns how to think. It's dirty politics, and Utah voters are smart enough not to fall for it."
