Bill Vivlamore, the president of the Frontier Supply Company in Fairbanks, is featured in a new Begich attack ad by Crossroads GPS. “Mark Begich doesn’t understand what voting 97 percent of the time with Obama is doing to businesses in Alaska,” says Vivlamore, who focuses in the ad on Begich’s vote for ObamaCare. The ad will run statewide and is backed by $450,000. Unlike American Crossroads, Crossroads GPS isn’t a super-PAC, and runs issue ads instead of ads advocating for a candidate. As such, it’s not required to disclose its donors.
