Frank Rich points out that McClellan's book has brought the Iraq war front and center. McCain is in a difficult spot:
Now Mr. McCain is chastising Mr. Obama for not having visited Iraq since 2006 — a questionable strategy, you’d think, given that Mr. McCain’s own propagandistic visit to a “safe” Baghdad market is one of his biggest embarrassments. Then again, in his frantic efforts to explain why he sided with Mr. Bush to oppose an expanded G.I. bill that the Senate passed by 75 to 22, Mr. McCain has attacked Mr. Obama for not enlisting in the military.
Besides making Mr. McCain look ever angrier next to his serene opponent, this eruption raises the question of why he chose double-standard partisanship over principle by not applying this criterion to the blunderers who took us into Iraq. Unlike Mr. Obama, who was 7 years old in 1968, Mr. Bush and company could have served in Vietnam as Mr. McCain did.
The McCain campaign may have no choice but to double down on Iraq — what other issue does the candidate have? — but it can’t count on smear tactics or journalistic and public amnesia to indefinitely enforce the McCain narrative. As the McClellan circus shows, unexpected bombshells will keeping intervening — detonating not only on the ground in Iraq but also in Washington, where more Bush alumni with reputations to salvage may yet run for cover about what went down in 2002-3.
