Public Policy Polling is out with some new post-debate numbers in Virginia, where Mitt Romney is campaigning tomorrow, and finds that President Obama still leads Mitt Romney there:

PPP's newest Virginia poll finds Barack Obama leading Mitt Romney 50-47 in the state, down from a 51-46 advantage three weeks ago. This is the closest we've found the race in Virginia the entire cycle, but Obama continues to find himself at the critical 50% mark in a state where Romney probably can't afford to lose.

Romney's performance in the debate on Wednesday seems to have helped his image with Virginia voters. They think he won the debate by a 61/28 margin, including 71/17 with independents. Compared to our last poll he's seen a 10-point gain in his net favorability rating from -2 at 47/49 in mid-September to now +8 at 52/44. The problem for Romney is that most of that gain has come with Democrats, from 6/90 to 21/76. But still only 8% of those Democrats are actually voting for Romney. Much of the improvement in Romney's image is people going from hating Romney and voting for Obama to respecting Romney but still voting for Obama.
