Remember that he's had chances to close her out before -- and whiffed. "Even as Obama campaign officials play down their chances of winning Pennsylvania -- asserting that anything less than a double-digit Clinton victory would be a triumph for the candidate -- his confrontational posture in the race's closing days suggests a newly adventurous strategy," Sasha Issenberg writes in The Boston Globe.
"The dramatic shifts in Obama's campaign in Pennsylvania reflect the lessons learned from earlier disappointments, when victories might have driven Clinton from the race," Dan Balz and Shailagh Murray write in The Washington Post. "He has questioned whether she is honest and trustworthy and cast her as a practitioner of old-style, special-interest politics."
This cuts both ways, over in the realm of spin: "Given how much they've thrown at us, and the all-out effort the Obama campaign has made to win, we don't believe that the margin matters that much any more -- just who comes out on top," said Clinton campaign strategist Geoff Garin.
Rep. John Murtha, D-Pa., still isn't reading his talking points: "I'd be surprised if she doesn't win by 10 points," Murtha said, per Jill Lawrence and Kathy Kiely of USA Today.
Gov. Ed Rendell, D-Pa., is reading his (for a day, at least): "Would I like [Clinton] to win by double digits?" Rendell asked on "Face the Nation." "Sure, but I don't think that is going to happen."
Or maybe not: "Not to put any pressure on you folks, but this is it, this is it," Rendell said Sunday in York, Pa., per NPR. "We're gonna we win, no doubt about it, but we gotta win big."
After saying "yes, yes, yes" at last week's debate to the question of whether Obama can win, Clinton offers a twist on that answer to the Philadelphia Inquirer's Thomas Fitzgerald (shades of her argument to superdelegates?): "I don't see any contradiction at all. . . . He can be elected; I will be elected. . . . If you look at the electoral map, anything is possible, but it is more likely that the coalition I have put together is the winning coalition."
The latest Quinnipiac poll out of Pennsylvania has it Clinton 51, Obama 44 -- almost exactly where the poll has been for two weeks.
McClatchy/MSNBC has it at Clinton 48, Obama 43 in Pennsylvania -- perilously close to the margin where a Clinton win won't be a "win" -- and in the territory where even a victory won't guarantee her a delegate edge. "Hillary Clinton leads among bowlers, gun owners and hunters in Pennsylvania, a blue-collar trifecta that is helping her hold an edge over rival Barack Obama heading into Tuesday's pivotal primary there," McClatchy's Stephen Thomma writes.
Pennsylvania is likely to show the Democrats their divisions, all over again. "The class issue looms the largest in Pennsylvania," Peter Canellos writes in The Boston Globe.
"Increasingly, the fear among Democrats is that one group or the other might opt for Republican John McCain, should their favored Democrat not get the nomination. And in places like Lawrenceville, a section of Pittsburgh, preferences have only hardened as voters have gotten to know more about the candidates."
Clinton's close is targeting Obama's base: "Sen. Hillary Rodham Clinton yesterday unleashed a steady barrage of attacks on Sen. Barack Obama, playing up her experience before a group that usually lines up behind her opponent -- students," Jerome Sherman writes in the Pittsburgh Post-Gazette.
