The field's turned upside-down. Here it is: the Des Moines Register's Iowa Poll.

1. John Kerry, 26 percent
2. John Edwards, 23 percent
3. Howard Dean, 20 percent
4. Richard Gephardt, 18 percent

It's close, and Dean and Gephardt are still thought to have the superior organizations heading into Monday's caucuses. But this is quite a turnabout, no? And organization might be offset by passion. Check out this paragraph:

In another sign of strength for Kerry, he is supported by 33 percent of those definitely planning to attend the caucuses. Dean comes in second in this group with 21 percent. Edwards and Gephardt follow with 19 percent and 16 percent, respectively.

Of course, this raises many, many questions. If Kerry doesn't finish first now, is it worse than if he had never held the lead? If he does finish first, do New Hampshire Democrats care? Those are just for starters.
