In her latest Op-Ad column for The Nation, Leslie Savan skewers the McCain "Joe the Plumber" commercial. It's worth following the link above, not just to read the column, but to see a hilarious Pepsi commercial using the most famous scene from Spartacus:

"One thing you've got to say about John McCain and his campaign gimmicks: He will blithely hold onto them like a pinless grenade until they blow up in his face, as he did with the Palin pick for veep, the 'suspension' of his campaign for the bailout, and now, of course, Joe the Plumber. McCain might yet get the real Joe Wurzelbacher to cut an ad for him, but in the meantime, the candidate has found a bunch of other oppressed 'just folks' to swear that they are all Spartacus, too."
