There's a reason political science professors are never to be found elected to anything. The fact is that we have an entire political party hoping desperately that evil fanatics who hate Americans will kill a few and pull their party's fortunes out of the garbage disposal. Hoping for disaster is one of those things that sounds great on paper but is ludicrous practical politics.
One simple illustration - say terrorists do whack us again, hard, in the U.S. - who does our professorial friend think the people will prefer to lead them in that event, Bush or Dean? Yeah. Me too.
