Uno Problemo, Senior McCain...

I still think the winning card -- if Obama wanted to stoop low enough to play it (at least as low as McCain's been playing, anyway) -- is immigration. It would take a bit of a reversal from Obama to steal a page from Bush/Roves "divide and conquer" playbook but I think it would be effective in a very evil way.

Mickey Kaus seems to agree:

Attention Ms. Coulter: John McCain is running an ad in Spanish attacking Obama for allegedly failing to support the "comprehensive immigration reform" bill that McCain himself has said he no longer supports. ... I guess McCain got the "message" but not the mensaje. ... P.S.: The picture of Sen. Patrick Leahy is especially terrifying. ... P.P.S.: Would McCain ever run this ad in English?
