During the Democratic primaries, I was obsessing over the polls, unable to resist checking realclearpolitics.com repeatedly to see what was changing. Now I'm obsessing over the vice-presidential picks, going back back back repeatedly to see if Obama has announced his choice, even though I get e-mail news alerts from several national media.

Pointless.

But you've gotta admit: there continues to be wonderful drama in this presidential-election year.

I'm not overly enthusiastic about any of the presumed Obama short-listers. I like them all, but I'd rather see Joe Biden as Secretary of State, and his penchant for being long-winded is the opposite of what Obama needs to balance the ticket. Nobody seems to be the sharp, elbows-flailing running mate that this campaign needs.

To me, the potential for real fun is in the McCain campaign. Either Tom Ridge or Joe Lieberman would be a delicious selection. Both are pro-choice. That's just what the Democrats need to have the Republican Convention dissolve into the chaos that the Clinton supporters seem to be planning for Denver next week.

But I can't help wishing: Please, please, McCain, pick Lieberman! Two old white guys, gung-ho on the war in Iraq. Obama should be able to beat that team with one hand tied behind his back.
