The latest Quinnipiac Poll shows Clinton leading Obama, 51-44%, while the latest Suffolk University Poll has her ahead 52-42%; also note that in this poll "20 percent of these likely Democratic voters said they would vote for John McCain in November if their Democratic choice does not win their party’s nomination."
The director of the poll (do note the name), David Paleologos, had this to say:
"Hillary Clinton’s projected win in Pennsylvania poses some serious problems for the Democratic Party at this point. First, it continues a bitter battle between the Democratic combatants; second, with 20 percent of core Democratic supporters fleeing to McCain, electability in November becomes a quantifiable problem; and third, it begs the question of who in the Democratic Party will become the ultimate peacemaker?"
My guess is that if Clinton actually wins Pennsylvania by 10 points or more, she will call it a major victory and say she defied augury despite the fact that everyone said she would win. She will assert this as proof that she can win in November (and Obama cannot) so she has an obligation to push on and nothing can stop her from going all the way to the convention. And the real agony for her party will start here. And I like this phrase from Drudge: "Controlled excitement is building inside of Clinton’s inner circle as closely guarded internal polling shows the former first lady with an 11-point lead in Pennsylvania!"
