A reader notes:

A few years ago, my house got broken into in the middle of my term in grad school. I was still expected to turn in my homework on time. McCain should debate.

If McCain were a rational candidate wanting to demonstrate leadership in a time of crisis, he would simply suggesting refocusing Friday's debate on economic issues, and holding it in Washington, D.C., so that he and Senator Obama could be present on the hill for a vote if one were to be called. Alas, he's yet again demonstrated a callow, vainglorious attitude in his campaign for the Presidency. He's demonstrably unfit for the job.
