David Broder, who has always had a soft spot for John McCain, writing in tomorrow’s Washington Post. Shorter Broder: Fork him.

This week, those voters are part of a mass movement to Obama, driven by much greater familiarity with the Illinois senator’s views and by a pronounced distaste for McCain and his running mate, Sarah Palin.

The striking shift in Montgomery County, often a bellwether, makes McCain’s task of recapturing Pennsylvania from the Democrats look almost like Mission Impossible.

Robert Stutz, a recently retired hospital administrator, was, like many of his neighbors, skeptical of both the eventual nominees when they were on the primary ballot, “so I was mostly listening to Hillary at that point.” But he’s been impressed with Obama’s health-care plan and says that McCain virtually disqualified himself with his vice presidential choice. “I can’t imagine putting Sarah Palin in a position to be president of the United States,” he said….

Ann Marie Cutler, another Clinton primary voter, admits that she still has “some doubts about Obama in terms of experience,” but she is reassured by the fact that “he’s very bright.” She watched the vice presidential debate and was “sorely disappointed” with Palin. She “drops her g’s constantly,” Cutler said.

Said Marjorie Lukens, a registered Republican: “The thought of Sarah Palin being a heartbeat away is terrifying.”

….She likes McCain as a person, but “I can’t understand why he keeps talking about this Ayers guy” — William Ayers, the 1960s radical who became an occasional colleague and supporter of Obama in Chicago. “He should be focusing on the economy and real terrorists; that’s what people worry about,” she said….

It’s hard to see how John McCain can overcome these odds in Pennsylvania.
