Paul Mirengoff at Powerline claims to have a hard time imagining how the Clintons would be able to smear John McCain, given his war record and status as a near national icon. Here's how:
She: Neither Senator McCain nor I want this race to be about age or gender.
He: I said I couldn't make Hillary younger or prettier. Fortunately Sen. McCain does both those things for me.
As she denies that age is an issue in the campaign (he'll continue to refer to it), count on a compliant media to spend at least a week on message on this one.
That bit about the media is tremendously important. Sen. McCain is used to getting favorable press treatment, and I suspect he's completely unprepared for the reversal on that front, which could well make his much less, "electable" than many of those voting for him suspect. On that score, a Republican who's used to dealing with the hostile media, such as Giuliani or even Romney, may well stand a better chance in November.
