The improving economy has turned President Obama's fortunes around in New Hampshire, according to a new WMUR Granite State Poll.

Some 51 percent of respondents now approve of Obama's job performance, up 10 points since October. Good news on the economy seem to be driving the change, with the percentage of people who think the country is on the wrong track dropping from 70 percent to 50 percent.

That shift translates to votes: Obama would beat New Hampshire primary winner Mitt Romney by 10 points, according to the poll. Obama would beat Ron Paul by 8 and Newt Gingrich and Rick Santorum by more than 20.

The poll of 527 adults was conducted Jan. 25 through Feb. 2, before Friday's jobs numbers came out showing a dip in the unemployment rate for the fifth month in a row, down to 8.3 percent.
