Report: McCain Nearly Quit Race In July.

TPM:

This can't be the kind of story that John McCain wants out there. In a new GQ write-up on how the one-time frontrunner's campaign fell into the doldrums, a source says that McCain almost dropped out of the race back in early July.

"As [longtime McCain aide Mark] Salter later confided to a top adviser, McCain was ready to quit the campaign then and there," the article alleges. "Salter talked him down as well."
At that point, the campaign was taking a lot of heat over fundraising problems, Iraq-related gaffes, and the failure of the immigration bill.
