From Fox News:
The president would take 49 percent of the vote compared to Romney’s 40 percent in a head-to-head matchup if the election were held today, the poll found. Last month, Obama had a four percentage-point edge of 45 percent to 41 percent. This marks the second time this year the president has had a lead outside the poll’s margin of sampling error.
Obama’s advantage comes largely from increased support among independents, who now pick him over Romney by 11 percentage points. Some 30 percent of independents are undecided. Last month, Obama had a four-point edge among independents, while Romney had the advantage from April through early June.
Partisan breakdown in the poll is 44 percent Democrat, 35 percent Republican.
