All over the place (link post) going into Pa.

There seems to be another growing wave of "Clinton can't win." (AP: Analysis: Time, Delegate Math Working Against Clinton, JoeKlein/Time)

And there seems to be a little evidence that alot of insiders are beginning to feel that it's over (or needs to be.) Howard Dean yesterday. CQ informal Congressional Insiders poll.

I think alot of it has to do with the Clinton camp trying to go negative. It doesn't seem to have worked.

Sens. Barack Obama and Hillary Rodham Clinton are both sustaining dents and dings from their lengthy presidential fight. The former first lady is clearly suffering more as Democratic voters no longer see her as the party's strongest contender for the White House.

The superdelegates seem unmoved as well, (NYTimes) Superdelegates unswayed by Clinton's attacks.

However, despite all the apparent movement on the national front, Pa. is still a Clinton win, and I would point again to Chuck Todd's observation from a couple days ago about the Pa. polling.

There's a pattern that ought to worry Obama: He is consistently sitting in the low 40s in the state(Pa.) In fact, his range is strikingly consistent, while Clinton's number is all over the map -- from the mid-40s to mid-50s. Does Obama have a ceiling in Pennsylvania? And does this mean a five-point lead for Clinton in these new polls today could quickly turn into a 15-point one if undecideds move en masse to Clinton?"

The CW seems to be that Clinton needs to win Pa. by at least 10, and that could happen. It's not unrealistic that Clinton could win Pa. handily, close the popular vote gap by a bit, and still come away with only a relatively small pledged delegate gain.

And then, two weeks later, Indiana's a functional tie and Obama blows out in NC, erasing any Pa. gains.

So, where would we be then? Right where we are now, except with no big states left.
