And, in the likely event that nothing shocking happens: "Rather than settle anything, the seven-week Pennsylvania contest is starting to look a lot like Groundhog Day, as polls show Clinton with a narrow lead," Brett Lieberman writes in the Harrisburg Patriot-News. "A victory for her on Tuesday could mean another six weeks of primary fights."
"As the race grows more negative, most signs indicate that Pennsylvania voters won't be the ones to end the historically long primary season," Rick Pearson and Mike Dorning write in the Chicago Tribune.
Before the voting resumes, Clinton continues to lose ground among the only audience that really matters. Another superdelegate moves to the Obama column over the weekend -- Nebraska party chairman Steve Achelpohl.
The New York Times' Mark Leibovich seeks to find out why so many F.O.B.'s have become quite friendly with another B -- at the expense of H. "After nearly two decades building relationships with a generation of Democrats, Mrs. Clinton has recently suffered a steady erosion of support for her presidential campaign from the party stalwarts who once formed the basis of her perceived juggernaut of 'inevitability," Leibovich wrote Sunday.
Said former Bill Clinton chief of staff Leon Panetta: "There is clearly a high frustration level among campaign types and from the Clintons themselves." (And this telling reaction from a "prominent Clinton supporter" to Sen. John Kerry's decision to criticize the former president's conduct: "And he was dead to us.")
Obama isn't the only one who needs to watch his words at fundraisers. Sen. Clinton's words from way back in February were reported Friday by Huffington Post's Celeste Fremon: "Moveon.org endorsed [Obama] -- which is like a gusher of money that never seems to slow down," Clinton said.
"And they are very driven by their view of our positions, and it's primarily national security and foreign policy that drives them. I don't agree with them. They know I don't agree with them. So they flood into these caucuses and dominate them and really intimidate people who actually show up to support me."
Obama may well win the race, but is the sheen coming off the new car? "Sometimes when he answered questions at the ABC debate, you could see white letters on a black background scrawling across the screen of a Republican attack ad," Maureen Dowd writes in her New York Times column.
"The thorny questions Obama got in the debate were absolutely predictable, yet he seemed utterly unprepared and annoyed by them. He did not do well for the same reason he failed to outmaneuver Hillary in a year's worth of debates: he disdains the convention, the need for sound bites and witty flick-offs and game-changing jabs."
Then there's Bill Ayers. On ABC's "This Week with George Stephanopoulos," Sen. John McCain, R-Ariz., made clear that he sees Obama's connection to the former member of the Weather Underground as fair game: "His relationship with Mr. Ayers is open to question," McCain said. "If you're going to associate and have as a friend and serve on a board and have a guy kick off your campaign that says he's unrepentant, that he wished they had bombed more."
