So now we've learned that Sarah Palin is McCain's choice for vice presidential nominee. I have to say, it's a daring pick but I think a very weak one. I'm perfectly happy with it. Palin is in the midst of a reasonably serious scandal in her home state. Her brother-in-law is a state trooper who is in the midst of an ugly custody battle with her sister. And she's accused of getting the state police to fire him. Recently she was forced to admit that one of her aides had done this, though she insists she didn't know.

Next, John McCain's central and best argument in this campaign is that Barack Obama simply lacks the experience to be President of the United States. And now John McCain, who is a cancer survivor who turns 72 years old today, is picking a vice presidential nominee who has been governor of a small state for less than two years and prior to that was mayor of a town with roughly one-twenty-seventh of the constituents that Barack Obama represented when he was a state senator in Illinois.

Whatever you think of Barack Obama's qualifications to be President, Palin is manifestly less qualified. And that undermines the central premise of McCain's campaign.
