Once again, the momentum in the 2012 presidential race is shifting. Though President Obama saw a surge in his poll numbers following Mitt Romney’s “47 percent” gaffe, the latest NBC News/Wall Street Journal numbers show that although Obama is maintaining his lead, Romney is “well within striking distance,” according to pollsters. Among likely voters, the new numbers show Obama leading 49 to 46 percent—an advantage that’s within the survey’s margin of error. Among the wider sample of registered but “less likely” voters, Obama leads 51 percent to 44 percent. According to NBC News, the two demographics most enthusiastic about Obama—Latinos and young voters—are less likely to vote in this election than they were in 2008.
