Twitchy reported earlier on a somewhat bizarre post-debate flash poll by Public Policy Polling showing President Obama winning the final presidential debate but losing the votes of Independents in the process.

PPP has other numbers out tonight, though, showing the results of a three-day (pre-debate) national tracking poll. In the poll, Mitt Romney leads nationally 49-47, with a D+6 sample. The survey also shows that 51 percent disapprove of the job President Obama is doing as compared to 45 percent who approve. Romney earns a 50 percent favorable rating to 45 percent unfavorable.
