Click to watch video 03:08 PM ET 10 reasons religious conservatives love Rick Santorum By Dan Gilgoff, CNN.com Religion Editor (CNN) - For all the attention paid to the clout of fiscally focused tea party conservatives and of the primacy of jobs in the 2012 election, Rick Santorum’s trifecta victories Tuesday night are a good reminder of the powerful role religious conservatives play in the GOP. They fueled Santorum’s wins in Missouri, Minnesota and Colorado - and his earlier victory in the Iowa caucuses. But why, exactly, do religious conservatives love the former senator from Pennsylvania? There are obvious reasons - his advocacy against abortion and same-sex marriage, for instance - but plenty of less obvious ones, too. Here’s my list. What would you add? Santorum’s a family man. “He’s got this big, vibrant family and he left the campaign trail last week to go back and be with his daughter in the hospital,” says Eli Bremer, chairman of Colorado's El Paso County Republican Party, centered around evangelical-heavy Colorado Springs. Santorum recently returned to Pennsylvania to respond to a health scare involving daughter Isabella - the youngest of his seven children - who suffers from a genetic disease. “I spent time with him last year, and he’s constantly thinking about his family,” Bremer says of Santorum. “It’s not just a political stunt.” He’s not averse to getting politically incorrect when donning culture warrior chain mail. “So if the baby’s toe is in you can’t kill the baby - how about if the baby’s foot is in?” he famously asked U.S. Sen. Barbara Boxer, D-California, in a 1999 debate over a rare, later term abortion procedure that anti-abortion groups call a "partial birth" abortion. Santorum’s a homeschooling dad. His wife, Karen, is homeschooling or has homeschooled their seven children, making them a poster family for a movement populated largely by evangelical Christians and other serious believers. “It matters because it shows he’s a real part of our movement rather than simply someone who is politically sympathetic,” says Michael Farris, an evangelical conservative who leads the Home School Legal Defense Association. He’s a devout cradle Catholic. As a kid in Pennsylvania, Santorum the altar boy would spend Sunday mornings pushing hospital patients in wheelchairs to Mass. As a U.S. senator, Santorum attended Mass at St. Joseph’s on Capitol Hill each day before work. That piety gets respect with religious voters, regardless of affiliation. “Evangelicals have made him an honorary evangelical,” said Richard Land, public policy chief for the Southern Baptist Convention. Santorum’s not Mitt Romney. Millions of socially conservative voters still distrust the former Massachusetts governor on the hot button issues - abortion and same-sex marriage. Some, though not all, are put off by Romney’s Mormonism. Santorum’s not Newt Gingrich. Many social conservatives, particularly those of the female persuasion, continue to be turned off by Gingrich’s two failed marriages and his admissions of past marital infidelity. Santorum doesn’t just talk about opposing abortion, he’s legislated on it. As a senator, he was an architect of the Partial Birth Abortion Ban Act of 2003. He pushed the ban even in the1990s, when Bill Clinton was in the White House and the legislation stood nary a chance of a presidential signature. “He walked the walk,” Land says. “When no one else would carry our water in the Senate, he would.” Ditto on same-sex marriage. Santorum sponsored a constitutional amendment to ban same-sex marriage at a time when many Republicans lawmakers didn’t want to touch such a hot potato. Santorum’s big on compassionate conservatism. Though he gets the most ink for controversial stances on issues such as homosexuality, Santorum has also been a leading advocate for funding to fight AIDS in the Third World and has led conservative responses to poverty. “A lot of people have a hard time getting Rick Santorum because they’re used to a debate between liberalism and complete free-market approach and he’s not either of those things,” says Michael Gerson, a Washington Post columnist and former speechwriter for President George W. Bush. Santorum isn’t afraid to challenge science, questioning the theory of evolution and dismissing global warming as “a hoax.” The former senator “confirms (social conservatives’) view of science as being at odds with a Christian worldview,” tweets Warren Throckmorton, a psychology professor at Grove City College, an evangelical Christian school in Pennsylvania.
