"The Alternative is Unthinkable"

Conservative writer and former editor of The New Republic Andrew Sullivan, again:

John McCain has demonstrated with this insane decision that he is unfit to be president of the United States. This was an act of near-criminal negligence. If he can behave this recklessly and impulsively with this decision, the idea of allowing him to become president of the United States is only a smidgen less terrifying than thinking of Palin in that position.

Whatever few doubts I may once have still had about this election, they are resolved now.

Obama has to win. The alternative is unthinkable.
