Still on the Rolling Temper Tantrum Tour ’08, Bill Clinton gave a revelatory radio interview yesterday. Losing his cool and discarding any remnants of good sense, he was in top meltdown form, complete with a not-quite-out-of-earshot bit of profanity. Here’s what we learned:

1. The fallout over his comparing Obama’s South Carolina primary victory to Jesse Jackson’s was a matter of the race card being used against him. Though he brought up Jackson in connection with Obama, any connection on basis of race was introduced by the Obama camp in an effort to smear poor Bill.

2. He knows this now for a fact, because of some unearthed memos from the Obama camp.

3. You have to work pretty darn hard to cast Bill Clinton as a racist because . . . he has an office in Harlem.

4. He doesn’t think he “should take any s**t from anybody on that, do you?”

Actually, he should. On that and a great many other things, Americans (especially his wife) are hoping against hope that Bill Clinton will pipe down, get humble, and disappear. His inability to do so approaches the pathological. What’s fascinating about this most recent interview is not the victim mentality, the paranoia, or the commercial real estate approach to civil rights.

It’s that nothing offered in this outburst could possibly help his wife in Pennsylvania today. The temptation to psychoanalyze candidates and their spouses is best resisted, but in the case of Bill Clinton no analysis is required. He’s openly telling you: He doesn’t think he should take s**t from anybody, campaign be damned. With delegate math making things nearly impossible for Hillary, it’s as if Bill has decided to try and fight for some obscure personal validation. Can there be any question that the Clintons are heading for a double defeat?
