To borrow from Ross Perot (not always a good idea), would you hire any of these people as a manager at your company?
Palin you’d offer the job to right away, and then you’d sweat until she accepted it.
McCain would seem like a decent choice, but wouldn’t make or break you either way.
You’d wonder how Obama possibly thought he was qualified, and you’d leave him to be hired by some other company where they fall for people who say all the right things.
And you’d be telling stories about Biden’s interview, and making jokes about it, for years.
