Feb. 21-24: Obama 51 Clinton 39
Mar. 3-5: Clinton 48 Obama 44
So that represents a 16 point swing in Clinton's favor in little over a week.
The other tracking poll, Rasmussen, has Clinton up as well (by 5 points).
Clinton has also gotten a bounce in Pennsylvania as well. She has also narrowed Obama's lead in North Carolina from double digits to only four:
“This isn’t actually particularly good news for Obama,” said Dean Debnam, President of Public Policy Polling. “He’s been leading in most North Carolina polls over the last three weeks by double digits. But as the national polls and last night’s results have shown Clinton inching closer, the same trend has occurred in North Carolina.”
For the moment, Obamania is stalling. It remains to be seen if Clinton can maintain her good run. Obama can try to hype Wyoming (which won't work), but if places like North Carolina continue to tighten up he will have a big problem on his hands.
And for all of us political junkies, the prospect of a brokered convention begins to loom large, since no one really believes either candidate will bow out now.
