From a reader:
Isn’t it obvious who McCain should invite to be his VP? Barack Obama. A McCain-Obama ticket would win 45 states, minimum. McCain is a Democrat anyway, and Obama’s positions become more like McCain’s with every passing hour. Hillary would get the Dem nomination and all of her supporters would be thrilled. Everybody wins. The only potential snag is that Obama is clearly lacks the experience and qualifications to be vice-president. But I think this can be glossed over.
