Obama picks up his fourth superdelegate of the day, Keith Roark of Idaho. One week ago, Roark tipped his hand:

"Every time I say this, it's a guaranteed applause line," [Bill Clinton] said. "You can drop me in the middle of Idaho where there's not a Democrat in 200 miles and an elk would applaud me on that."

Idaho Democrats called Clinton's comments an insult. They said the state party is making a comeback - after suffering setbacks during Clinton's two terms in office.

"If Bill Clinton had done for elk in Idaho everything he did for Democrats, we'd have far fewer elk," said Idaho Democratic Party Chairman Keith Roark - an uncommitted superdelegate - Wednesday morning.
