Senator McCain will vote "no" on Kagan -- Is he serious?

Just yesterday, Senator McCain announced his intention to vote "no" on General Kagan's nomination to the Supreme Court.  Clearly, that is his prerogative.  What I find far more amusing are his stated reasons for his vote.  Does he think we are that stupid?

The Senator began with a very serious -- and promising -- charge: "In 1987, I had my first opportunity to provide 'advice and consent' on a Supreme Court nominee. At that time, I stated that the qualifications essential for evaluating a nominee for the bench included 'integrity, character, legal competence and ability, experience, and philosophy and judicial temperament.' On that test, Elena Kagan fails." These are all good reasons for voting down a judicial nominee.  The better question is how Senator McCain reached the conclusion that Kagan failed on any of these metrics.  What exactly persuaded him that she was not fit to join the Supreme Court?

Turns out, she failed McCain's fuzzy test on one piece of evidence alone: her approach to military recruitment while dean at Harvard law.

I don't know whether to laugh or cry.
