This isn't much of a diary, but relevent to recent posts. I've been wondering if Hilary's strong trend to the negative and identification with John McCain would have an impact. The recent tracking polls seem to show a significant Barak Bump:
Rasmussen: H 46% O 45% (+5 one day swing to Obama)
Ras. Poll
Gallup: H 46% O 45% (+3 one day swing to Obama)
Gallup
I hope this keeps up. I wouldn't like to think Dem's would reward this kind of campaigning.
