THE BIG ENCHILADA:

The poll found Obama now has a 49-to-48-percent advantage over Romney among likely voters in the battleground state.

PPP said Romney was able to tighten the gap in Ohio due to his seven-percentage-point lead over Obama among independents and a boost in Republican voters reporting that they plan to vote for the former Massachusetts governor. Roughly 90 percent of the Ohio Republican base said they would support Romney, up from 85 percent who gave the same answer a week ago.

The president also lost his advantages over Romney on two top issues: the economy and Libya. Romney leads Obama in Ohio on the economy by four percentage points. On Libya, Romney's lead was two percentage points. 

Half of Ohioans disapproved of Obama's job performance, compared with 48 percent who said they approved of it.
