Here’s Republican candidate Lt. Gov. Mead Treadwell’s first widespread radio ad of the campaign season. The spot is airing along with a television ad introducing the theme, “The True Alaskan Conservative.” (I’ll post the TV ad when I get it, but it’s basically a cut version of this one.) What makes him more conservative than the other GOP challengers in the race –Joe Miller or Dan Sullivan — is anyone’s guess. But that likely won’t matter. Treadwell’s message is clear and to the point, and is one that the public will likely remember if Treadwell has the money to be able to disseminate the ads widely enough. Whether they’ll believe it is another story.
