Idaho Gov. Butch Otter has launched a new campaign ad in the final days before the election, featuring former GOP presidential candidate Mitt Romney endorsing him. Romney urges Idaho voters to “get out and vote,” and says, “What’s happening under Butch Otter ought to happen to every state, and you’re lucky to have this man as your governor.” The ad is running statewide both on TV and radio, Otter’s campaign said, including the Spokane broadcast TV market. Romney’s comments came during a campaign stop for Otter and GOP Sen. Jim Risch in Boise last week; Risch also has a new TV ad out featuring Romney’s endorsement.
