Although he has yet to go on the air, New Hampshire Republican John Sununu has received a boost from conservative nonprofit Citizens United as he attempts to defend his Senate seat from former Gov. Jeanne Shaheen (D).

“Who could have guessed how the Internet would change our lives?" an announcer asks in the new ad, "Innovation" (subscription), which hit New Hampshire airwaves late last week. "Fortunately, Senator John Sununu leads the battle in Washington to defeat Internet taxation schemes."

The ad concludes by highlighting Sununu's efforts in Congress, such as sponsoring a measure that would permanently free the Internet from taxes.

"Citizens United is an organization dedicated to the principles of lower taxation and limited government, so we believe very strongly that the Internet should remain free from government interference and tax collectors," said organization spokesman Will Holley. "And Senator Sununu has far and away been the leader for preventing that from happening."

Shaheen released her debut ad on May 20.
