Here’s the latest ad from the pro-Mark Begich super-PAC Put Alaska First. It’s the first television ad the PAC has released that includes Mead Treadwell. Take that for what you will. Polls have shown that Dan Sullivan is leading the primary-pack. But Put Alaska First is also polling, and it might see things that other pollsters aren’t. Anchorage-based Jim Lottsfeldt, who runs the PAC, declined comment on whether or not the PAC is going to air another ad before next Tuesday’s primary.
