Hillary Clinton got crushed in Wisconsin and has had a bad February, which makes todays new polls kind of surprising. Keep in mind that, as of a couple days ago, Obama was up 7 in the national polls and that he pulled to within 5 in Texas before Wisconsin's primary.

Caveats apply, of course, but I think it's clear that there's still a lot of room to move in this race, thanks in large part to proportional delegate allocation. If the Obama backlash is on the horizon, Clinton will get an opening that she's got a decent shot of taking advantage of. Either way, the continued splitting of national Democrats is going to make convention season very interesting.
