From anyone else, obnoxious, but done with Shapiro's trademark wit and clear eye, I think it's worth reading.

The Non-Hillary Field: Start with Mark Warner and 2004 V.P. candidate John Edwards, who are unabashedly running. Indiana Sen. Evan Bayh has privately put his own odds at 90 percent, and the latest word from Iowa is that Gov. Tom Vilsack is similarly poised to run. Wisconsin Sen. Russ Feingold -- who wins headlines every other week with an anti-Bush gambit like a censure resolution -- has to be counted among the likeliest contenders. And finally, Sen. Joe Biden, the Delaware motor-mouth who performed so garrulously during the Alito confirmation hearings, keeps insisting that he's definitely running.
Depending on whom you talk to, John Kerry is either running or merely keeping his options open for a mid-2007 decision by maintaining his visibility and e-mail list. (An e-mail appeal from Kerry raised over $100,000 for Tammy Duckworth, an Iraq war veteran running for the House in Illinois.) Al Gore represents another puzzle; his wife, Tipper, is said to be definitely opposed, while his politically active daughter Karenna seems severely tempted. Bill Richardson is seriously mulling his chances, while former Senate Majority Leader Tom Daschle is also playing the maybe game. And don't forget former Gen. Wesley Clark, who has never lacked ambition or self-confidence.
How to Think About the Field: Like old-fashioned slot machines, the final round of most presidential races comes down to three possibilities. (Granted, there have been a number of past years when pushing the lever produced three Democratic lemons.) The conventional method is to group the contenders in starkly different terms. There would be the left-wing political purist option, which would right now go to Feingold, though Gore and even Kerry could make claims based on the fervor of their antiwar rhetoric. Hillary, of course, would have an Heiress Apparent slot of her own. And the final position would belong to the winner of the Democratic Electability Bake-off: Warner, Edwards and Bayh are all vying for that honor. Yes, JPW, you're in this final mix with your landslide border-state reelection victory and, yes, the "Tennetucky Miracle."
But there is another way to slice and dice the 2008 wannabes. And that is to assume that the race will ultimately come down to Hillary, one intriguing fresh face (Warner, Bayh, Feingold, JPW, etc.) and one sadder-but-wiser repeat candidate (Gore, Kerry, Edwards, Clark or even Biden). The importance of these slots is to figure out who is vying against whom for supporters. Are Feingold and Warner battling to be the candidate of the blog-based "netroots"? Or is Warner, say, locked in a battle of Southern pragmatists with Edwards?
