Rick Santorum, the former senator from Pennsylvania who announced his candidacy for president on Monday, may not have a great shot at winning the GOP nomination, but might very well succeed in moving the Republican debate on social issues even further to the right than it has already become.

Today, Think Progress caught Santorum on video expressing a truly extreme position on abortion rights. Discussing his role in bringing about the federal late-term abortion ban, Santorum dismissed exceptions meant to protect the health of the mother as “phony” and claimed that such exceptions would render the ban “ineffective”:

Heartless remarks like these have earned Santorum the reputation as one of the most hard-right politicians on the national stage. Today, People For’s Michael Keegan posted a retrospective of Santorum’s career in the Huffington Post, writing about Santorum’s history of making dehumanizing remarks about women, gays and lesbians, Muslims, and victims of sexual abuse:

Santorum has a social issues record to make the Religious Right cheer. He made a name for himself on the national scene with his attacks on gay rights, most notably in a 2003 interview comparing gay relationships with “man-on-dog” sex. (In the same interview he argued that the Constitution does not protect a right to privacy. Recently he said that allowing loving gay couples to adopt children is “trying to defy nature” and should be illegal, as should gay marriage. He says that the Obama administration’s decision to stop defending the Defense of Marriage Act in federal court meant that the “free exercise of religion will be eviscerated.”

Although, while in the Senate, Santorum supported the occasional pro-choice Republican, he calls Roe v. Wade a “monstrosity” and supports criminalization of abortion, which he says is the reason Social Security is in trouble. He backs right-wing attacks on funding for Planned Parenthood’s family planning services, actively taking part in the right-wing propaganda campaign against Planned Parenthood. Santorum has slammed the Griswold decision, in which the Supreme Court recognized a constitutional right to privacy and overturned a state ban on contraception, as a “constitutional wrecking ball.”

Santorum gave Religious Right activists a powerful tool for pushing religion into public school classrooms when he sponsored an amendment to the “No Child Left Behind” law that encouraged the teaching of intelligent design in science classes. The amendment, written in part by the creationist Discovery Institute, became a force behind creationists’ bogus “teach the controversy” strategy. Santorum wrote in 2002 that “Intelligent Design is a legitimate scientific theory that should be taught in science classes.” Scientists and courts disagree.

Santorum has been a severe critic of Islam from his perch at the “America’s Enemies” program at the right-wing Ethics and Public Policy Center. He says Islam is incompatible with western civilization because Shariah is both a civil code and a religious code. But he also says of Christians that “it is our obligation” to make civil law in America “comport with God’s laws.”

Santorum has tried to get attention to his desire to be the second Catholic president by slamming the first, saying he was “appalled” by John F. Kennedy’s “radical” support for the separation of church and state – a centerpiece of Kennedy’s vision of America. Speaking of the Kennedys, Santorum criticized church officials for praising former senator Ted Kennedy at his funeral, saying there was “no excuse” for it and arguing that it was harmful to send the message that it was okay for Catholic politicians to dissent from church teachings.

Although Santorum has been quick to slam progressive Catholics for not hewing closely enough to the doctrine of Church hierarchy, he’s shown no compunction in casting aside Church teaching when it conflicts with his extreme ideology, as he did when repeatedly supporting “enhanced interrogation” techniques like waterboarding — which has been clearly labeled “torture” and “an intrinsic evil” by the Catholic Church. Santorum blamed the church’s sex abuse scandal on the liberal political culture of Boston:

“Priests, like all of us, are affected by culture. When the culture is sick, every element in it becomes infected. While it is no excuse for this scandal, it is no surprise that Boston, a seat of academic, political and cultural liberalism in America, lies at the center of the storm.”
