Rick Santorum ‘open’ to running for president again

Rick Santorum, the former Pennsylvania senator who ran for president this year, says he is considering a second campaign for the White House in 2016.

During a visit to Capitol Hill Monday, Santorum told The Weekly Standard magazine that he is "open" to running again.

"I'm open to it, yeah," Santorum told reporter Michael Warren. "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."

Santorum surprised many Republicans by securing the most votes in the Iowa caucuses in January, the first electoral contest of the presidential election cycle. He went on to win 11 states in total before dropping his bid and conceding to Mitt Romney in April.

Since then, he has launched an advocacy group called Patriot Voices and written a book, "American Patriots: Answering the Call to Freedom."
