The shift in public opinion on gay marriage has not had much impact on Capitol Hill, Politico finds. Asked if his views on the issue were changing, Sen. Saxby Chambliss (R-Ga.) replied, “I’m not gay. So I’m not going to marry one.”

Other senators gave less colorful responses, but the overall takeaway is the same. While Ohio Sen. Rob Portman's embrace of gay marriage has been largely accepted by his party, most of his Republican colleagues will not be joining him any time soon. Some vulnerable Democrats up for reelection in 2014 are also hoping to avoid the issue.
