Former Senator Rick Santorum, R-Pa., has consistently been a vocal critic of same-sex marriage and is making his conservative social beliefs a major part of his presidential platform. When asked whether he would accept the Supreme Court’s ruling if they legalize same-sex marriage later this year, he said he would "fight it."

"I think it's important to understand that the Supreme Court doesn't have the final word. It has its word. Its word has validity. But it's important for Congress and the president, frankly, to push back when the Supreme Court gets it wrong," said the presidential candidate on NBC’s "Meet the Press" Sunday.

He went on to say that the country is not "bound by what nine people say in perpetuity" and that he’s continued his fight against Roe v. Wade, the 1973 Supreme Court decision that affirmed a woman’s right to an abortion, because he thinks "the court got it wrong."

When asked whether he thinks states should ignore the ruling if the Supreme Court does legalize same-sex marriage, Santorum responded, "I don't advocate civil disobedience. I do advocate the role of an informed citizen to try to overturn when a court makes a mistake and gets an issue wrong."

Santorum announced he was running for president this past Wednesday. When he ran in 2012, he was the runner up to the GOP nomination and surprised many with his strong showing in the Iowa Caucuses that year. However, A Bloomberg Politics/Des Moines Register poll out Saturday night shows him tied with Republican Sen. Marco Rubio of Florida for sixth place in the state of Iowa.
