Are these the final figures released right before the elections or from a similar time frame as the current race?
However, Battleground shows less wild swings; and I think its methodology (as has been proven) gets a much better snapshot/cross-section of where voters actually stand at a given point in time.
Gallup shows as much as 12-20 point swings, which I find a fantasy - and we all see the breakdowns in Party ID in the media-sponsored polls.
Rasmussen used to worry me, but he has so oversampled Democrats that he didn't even show a convention bounce for McCain - until he adjusted for more Republicans to show that bounce, having seen his folly - then went right back to oversampling Democrats.
Rasmussen has a 6% Dem edge in turnout - in 2004 it was 47/47. The most it has EVER swung in one election was 4 points. In 2006 - a Dem landslide year - the Party turnout margin was Dems +3%.
If we readjust most of the polls - even many of the “RV” and “Adults” polls - for a more reason able 1-4% Dem edge instead of the gap they use, you get a statistical tie with a sometimes very slight, statistically insignificant edge for Obama.
It is more a dead heat right now that some of the polls show. Battleground, history's most accurate pollster - period - shows the same.
