A new NBC/Wall Street Journal poll out tonight shows President Obama at 50 percent among likely voters, and Mitt Romney at 45 percent. Among registered voters, Obama is at 50 percent support to Romney’s 44 percent. Among registered voters polled, 42 percent are Democrat or lean Democrat, while 37 percent are Republican or lean Republican. That  gives Democrats a +5 advantage — less than they enjoyed in 2008, when exit polls showed a +7 Democratic advantage, but more than in 2010, when Democrats and Republicans were tied for percentage of the electorate. 

Half of those polled think the economy will either stay the same or get worse in the next year, but when it comes to who’s better on the economy, Romney and Obama are tied, both receiving 43 percent support. When it comes to who would be better at looking out for the middle class’s interests, Obama has a 19 point lead, 53 percent to Romney’s 34 percent.
