A pro-Republican super PAC supporting Florida Rep. Connie Mack's Senate bid unveiled an ad buy in Florida media markets Thursday to marry up with President Barack Obama's campaign swing through Florida, Politico reported.
Mack, who acted as a surrogate for Mitt Romney's presidential campaign by attending the events of Romney's competitors during the Republican primaries, is running against Democratic Sen. Bill Nelson, who is mentioned as the "state liberal" in the ad.
