Former Pennsylvania Sen. Rick Santorum said Monday that he had not ruled out another run for President of the United States.


"I’m open to it, yeah," Santorum told the Weekly Standard. "I think there's a fight right now as to what the soul of the Republican party's going to be and the conservative movement, and we have something to say about that. I think from our battle, we’re not going to leave the field."

The staunch social conservative ended his bid for the nation’s highest office in April after his 3-year-old daughter Bella became seriously ill. Santorum was trailing nearly 400 delegates behind Romney and had slim chances of winning the Republican nomination.

During his campaign, Santorum vowed to limit abortion, ban same sex marriage, crack down on Internet pornography, repeal Obamacare and cut taxes. He also pledged to aggressively defend Israel and confront Iran over its nuclear program.

Santorum told the Weekly Standard that Romney should have made the 2012 election a referendum "on what it means to be an American." He said Romney did a poor job of showing the American people that Obama was leading the country towards "European socialism."
