BLUE ASH, Ohio (AP) -- Three of the four Republicans vying for the presidency are campaigning in delegate-rich Ohio ahead of the Super Tuesday contests.

Mitt Romney, Rick Santorum and Newt Gingrich were fighting Saturday for the state. Texas Rep. Ron Paul was set to campaign in Alaska.

Santorum spoke at a rally that drew hundreds in a conservative suburb of Cincinnati. He called for fewer children born out of wedlock and fewer single-parent families.

Romney said he'd push for states to take over operation of programs such as Medicare, Medicaid and food stamps. The Dayton Daily News reports his comments came at a town hall held at an aerospace and defense manufacturer in Beavercreek.

Gingrich, a former House speaker, also campaigned in suburban Cincinnati, saying he thinks he can win delegates in the state.
