A new radio ad chastising former Gov. Jeanne Shaheen (D) is the target of a complaint filed last week by the New Hampshire Democratic Party with the Federal Elections Commission. State Democrats allege that the nonprofit group Americans For Job Security has violated elections laws by disguising itself as an issues organization while running political advertisements on behalf of Shaheen's opponent in the Senate campaign, incumbent John Sununu (R). Americans For Job Security President Stephen DeMaura called the claims "completely baseless."

"Shaheen pledged to oppose any new taxes," an announcer says in "Taxes Hurt" (subscription), "but she broke her pledge and proposed millions in new taxes -- taxes that hurt New Hampshire, taxes that hurt families, taxes that have cost New Hampshire jobs." Another announcer urges viewers to call Shaheen and "tell her to oppose higher taxes on New Hampshire families."

This is the first race the group has engaged in for this election season, but it is looking at "multiple" contests throughout the country, DeMaura said.
