Today’s Good News for Romney: Mitt Romney used to like gun control. So did Barack Obama. Now both candidates support virtually the same broad range of gun rights—but only Mitt Romney has been endorsed by the National Rifle Association, the powerful pro-gun lobbying group that once feared supporting a candidate who has very publicly endorsed strong gun control measures in the past. Recently the NRA revealed that it has purchased more than $1.3 million worth of anti-Obama television advertisements in the battleground states of Ohio, Florida, Wisconsin, and Virginia. The Romney campaign’s attempts to craft a pro-gun image, aided by Paul Ryan’s love of hunting, has clearly worked, and the super PAC ads are hitting at a key moment as Romney builds momentum in those critical states.
