Are You Smart Enough to Be a Religious Bigot in the Voting Booth?

Whenever he was asked about the impact of his race on the 2008 election, President Obama would predict that while his race may cost him some votes, it might gain him some votes, just like a lot of other characteristics over which he has little to no control. Of course, as we later learned, there was another trait President Obama has little control over that had, and continues to have, the potential to cost him and other candidates even more votes than race: perceived religious beliefs. The fact that one in five Americans believe President Obama is not a Christian and view that as a justification for questioning his leadership and patriotism represents a political landmine for the president, one that increasingly his 2012 GOP opponents are in danger of stepping on as well.

Newt Gingrich's win in South Carolina has now made the unthinkable not just possible but virtually certain: a non-evangelical Christian is poised to become the Republican nominee for president. Of the four remaining candidates, just one Dr. Ron Paul, is a protestant. Two, Rick Santorum and Newt Gingrich, are practicing Catholics, while former frontrunner Mitt Romney is Mormon. Though I know this will elicit a lot of angry comments from Paul supporters, by now everyone besides them seems to know that he has as much chance of becoming the GOP nominee as I do. This means that the party for which faith has been as fundamental as family values (in messaging at least) will soon join the thousands of Americans each year who embrace another religion for love, or more specifically for marriage; in this case, a political marriage of convenience. (It's worth noting that Gingrich did this, quite literally, converting to Catholicism at the behest of his third wife.)

But here's a question. As we have evolved into a country in which divorce, out-of-wedlock births, premarital sex and other religion-inspired one-time taboos have lost most, if not all, of their stigma, why do we continue to be a country in which our religious beliefs significantly affect how we vote? A Gallup poll taken just months ago found that 22% of Americans -- across party lines -- will not vote for a Mormon candidate. Keep in mind that like discussions of race and sex, religion is a topic about which some people lie out of embarrassment, which means the number of Americans possessing some religious bias about Mormons, or any other group, is likely even higher than the numbers contend.

A 2007 survey found that 46% of Americans said they would be less likely to vote for someone who is Muslim but that pales in comparison to the number who said they were less likely to vote for an atheist: 63%. As of 2011 that number is still holding pretty steady at 61%. In fact a separate study released just last month found that atheists are as distrusted by Americans and Canadians as rapists. Yes, rapists. (Click here to see a list of atheists who have been elected to office along with other religious trailblazers in American politics.)

Religious prejudice has officially become one of the last remaining bastions of surface-based voter bias, with the number of Americans saying they would not vote for a racial minority, a woman, or a gay American decreasing significantly in recent decades. This is somewhat surprising for a number of reasons. For one, it is arguable that religious labels alone mean very much. For instance, Sen. Ted Kennedy and his brothers were devout Catholics, yet their interpretation of their faith and its role in their politics is miles apart from the interpretation of Sen. Santorum.

But perhaps the most ironic thing about all of this is that according to yet another study, an overwhelming majority of those who believe in God are ignorant of basic Biblical facts, and facts about other religions. A 2010 Pew study found only 2% of those surveyed could answer 29 of the 32 questions asked correctly. Most could answer about half. This means that people who aren't well-versed in their own religious beliefs, or anyone else's, are making decisions in the voting booth fueled by prejudice that isn't even well-informed prejudice.

You know who is well versed in religion, and well-informed too? Atheists, that's who. They were among the top scoring groups on Pew's religion pop quiz. Mormons also scored well. (You can test your own knowledge with questions from the quiz here.)

So this begs the question. If most of us are not knowledgeable enough of our own faiths to truly know if another faith is at odds with our own, then how can a vote based in part on someone else's designated religion be rooted in anything other than prejudice?

Though the Romney campaign has certainly been plagued by its own share of candidate-made missteps, it is hard to believe that were he a Methodist, instead of a Mormon, that Mitt Romney would be struggling the way that he is. As far as candidates go, he is practically perfect on paper, checking every box a political consultant could dream of for a "Franken candidate" resume, except of course one. (Some political analysts have even speculated that his tax release debacle was bungled in part out of fear of allowing already jittery evangelical voters to see just how much of his fortune the governor has donated to the Mormon Church over the years.)

When family values obsessed, evangelical die-hards who normally consider one divorce grounds for suspicion, two divorces grounds for derision, and proven adultery grounds for candidate ineligibility, choose Newt Gingrich over the guy who's been with his wife for life but just so happens to be Mormon, that tells you something about the role religious prejudice continues to play in American politics. The bigger question of course becomes whether or not Mitt Romney will ever have the temerity to say so out loud, or if it will take losing the nomination for him to finally understand and acknowledge that forms of bigotry still exist in America, and still hold people back.

For some people it may be their skin color keeping them from a job that they need. For others it may be their religion keeping them from the presidency they so desperately want.

Question: Would you be willing to vote for a candidate who practices a different religion than your own or doesn't practice one at all? Please share your thoughts in the comments section below.
