Florida Senator Marco Rubio and former Arkansas Governor Mike Huckabee are helping fellow Republican Mitt Romney by recording anti-gay marriage robocalls for the National Organization for Marriage (NOM).

The calls are being dispatched to voters in 3 states where marriage equality is on the ballot – Maryland, Maine, and Washington state – and presidential tossup states Wisconsin, Ohio and Pennsylvania, gay weekly the Washington Blade reported. (Minnesota does not allow such calls.)

Also participating in the calls is James Dobson, co-founder of Focus on the Family.

NOM President Brian Brown said the campaign would reach 10 million voters at a cost of $500,000.

“Even in these tough economic times, people know that the stability of the family is crucial and the need to preserve the institution of marriage has never been greater,” Brown said. “These calls from leaders in public life will remind voters to go to the polls, to protect marriage, and to support public officials who will do the same.”

Brown, whose group is heavily invested in the four state campaigns opposing marriage equality, predicted a “triumph for marriage and family” on November 6.
