McCain's Ayers

So McCain is predictably trying to tie Obama to some irrelevant but scary-sounding Mideasterners (who all seem to be Ivy League profs--very dangerous, guys) as well as Ayers. Obama's campaign seems to have forgotten that they are not required to counter this with something that's also kind of frivolous. What about Chalabi? There's probably a picture of him and McCain holding hands somewhere, and it's a relevant association. Come on.
