McCain's Veep

NRO's Jonah Goldberg suggests the unthinkable - that McCain should run with a Democrat - someone like Joe Lieberman or Sam Nunn. I don't know what to think about that. It would be a very unconventional choice, to say the least.

On the positive side, it would undermine Obama's claim to be the candidate of change, and it would highlight his extremism. It would also present Americans with a "national unity" ticket at a time when unity - particularly with respect to the war in Iraq - is in short supply.

So, what are the negatives? Choosing a center-left Democrat like Lieberman would be certain to annoy a few conservatives (like me), but if it were McCain-Nunn, I'd vote for that ticket in a heartbeat. It probably won't happen, but it's an intriguing possibility.
