Sen. John Sununu (R-N.H.) is getting some help from a conservative third-party group running favorable advertisements in his state. The first-term Senator faces a challenging rematch against former Gov. Jeanne Shaheen (D) in November.

Citizens United on Friday launched a television advertisement, “Innovation,” hailing Sununu’s efforts to keep the Internet from taxation.

“Who could have guessed how the Internet would change our lives?” an announcer asks in the ad. “But while we dream of even more innovation, some politicians dream of more taxation. Fortunately, Senator John Sununu leads the battle in Washington to defeat Internet taxation schemes. Sununu helped deliver the 2007 Internet tax moratorium. And he’s pushing to keep the Internet tax free permanently.”

The ad will air for an undisclosed period of time. Shaheen’s campaign is already airing a television advertisement — a biographical spot reintroducing her to voters.
