ObamaPollSplosion: He Breaks 50 Everywhere

You sort of need a ticker to follow it all.... CNN/ORC Florida: Obama at 54% among registered voters (really)...Obama up by four among likely voters in Nevada...up by double digits in Minnesota...tied in Missouri...nine points ahead among likely voters in Virginia...polls from Time...NBC News/WSJ/MySpace......the AP...

The same Democrats who three weeks ago were chanting to themselves "polls reflect the daily news, polls reflect the daily news"  are now enthusing about a blitz of state polls showing Barack Obama up everywhere, above 50 percent everywhere and even nationally.

I'm getting lots of e-mails speculating about the 2012 frontrunner for Republicans. (I think it's Huckabee, but that's for tomorrow.)

The trend lines are positive for Obama, and, of course, one would expect Democrats to cheer the good news.  (McCain's doing fine in..Oklahoma.)

Maybe this is something the polling experts can tell us, but have the polls ever swung this much, this late, and NOT swung back?  (And even if they've never done this before, is there anything fundamental about the nature of public opinion that prevents them from swinging back?)
