Andrew Sullivan has been making this case for some time on his blog, and has written up an excellent full-length article that should be a must read for any American who cares about his or her nation's direction:
Who does John McCain think he's kidding? And what on earth was he thinking? This was a rash, impulsive, reckless pick. We have no idea where it's headed - and i wouldn't hazard a wild guess what we will have found out about Palin in a week's time. Maybe it will win some votes from evangelicals. Maybe Palin will reveal herself as something more than a former sportscaster who can deliver a speech. But it shows a deep unseriousness about governing the most powerful nation on earth at a time of great peril.Don't worry, Andrew. I am.
If you thought a president who went to war on flawed intelligence with no plan for the aftermath was reckless, then I have news for you. You haven't seen anything yet. Imagine the kind of decision-making McCain has just demonstrated applied to ife-and-death decisions with respect to Iran and Russia.
Yes, you have permission to be afraid.
