More On The Four-State Pledge: Two Sign, One...

Two Democratic presidential candidates, Gov. Bill Richardson and Sen. Chris Dodd, have pledged to "honor the status" of Iowa, New Hampshire, South Carolina and Nevada by refusing to actively campaign in states found to be violation of the Democratic National Committee's delegate selection rules.

Does that mean that Richardson, potentially the first Hispanic president. won't participate in the first Hispanic language debate of the cycle -- next week's Univision debate at the BankUnited Center at the University of Miami? Yes -- he still can, according to the four-state consortium.

Mo Elleithee, a spokesman for Hillary Clinton, said that the campaign "received the letter and we are reviewing it. Sen. Clinton is 100% committed to campaigning in Iowa, Nevada, New Hampshire and South Carolina. She believes that these four states have a unique and special role in the process. There are other states that are going through a process now and we are going to let that process play out. But no matter what happens with those states, that will not affect our committment to these four states and we will compete in those states no matter what day those primaries or caucus are held."

The campaigns of Sen. Joe Biden, Ex-Sen. John Edwards, and Sen. Barack Obama have yet to respond.
