One on One

Hillary is keeping the pressure on over Barack's refusal to debate.

Clinton took the debate dispute to a new level, challenging Obama to face off with her in a debate without a moderator, Lincoln-Douglas style.

"Just the two of us, going for 90 minutes, asking and answering questions, we'll set whatever rules seem fair," Clinton said while campaigning in South Bend.

Her campaign made the offer formal with a letter to the Obama campaign.

Obama aides said he had already debated Clinton 21 times, "the most in primary history."

Considering that his refusal to debate follows his worst debate performance yet, wouldn't he be better off to do another?

And considering that this looks like the politics of old from Barack (don't debate when you've got the lead - why risk blowing it?), isn't this a violation of his brand?

And finally, considering that Hillary will haunt him with requests like this that make her look good, why is it worth it to take the heat?

Because in Barack's mind, and in reality, he's already won. It's time to play a conservative game, and fantasize about remodeling the white house.

On the other hand, Barack's refusal to debate Hillary gives him time to finally make good on his commitment to Chris Wallace to appear on Fox News Sunday.
