Frank Rich shares his thoughts on McCain and his 'Stroll in the market'.

Not only was a 'Dukakis in the tank' moment for McCain, it also marks a point where the other Republican presidential hopefuls will have to pull back on the 'Stay the course' insanity...

It can’t be lost on those dwindling die-hards, particularly those on the 2008 ballot, that if defending the indefensible can reduce even a politician of Mr. McCain’s heroic stature to that of Dukakis-in-the-tank, they have nowhere to go but down. They’ll cut and run soon enough. For starters, just watch as Mr. McCain’s G.O.P. presidential rivals add more caveats to their support for the administration’s Iraq policy.
