From Public Policy Polling, a firm that typically surveys for Democrats and liberals (Note: the poll differs from a Miami Herald survey last week, which had a 7-point Mitt Romney lead, although both show a Romney surge):
PPP's newest Florida poll finds a 5 point gain for Mitt Romney over the last three weeks. He now leads Barack Obama by a 49/48 margin, after trailing 50-46 in late September. The shift in the race is largely attributable to independent voters shifting their preferences. Where before Obama had a 51-40 advantage with them, now Romney's taken the lead by a 51/43 spread. When it comes to the biggest issue in the election, the economy, Romney's edge over Obama expands to 51/46 on who voters trust more.
Romney and Obama's images have headed in difference directions since the Presidential debate. Voters have warmed up to Romney a good bit, going from giving him a negative favorability rating at 44/51 to a positive one at 50/47. Meanwhile Obama's approval numbers have gone the other way. Where before he was on positive ground with 51% of voters approving of him to 47% who disapproved, now he's in slightly negative territory at 48/50.
