Honoring A Pledge

Last autumn when Florida and Michigan leapfrogged ahead of the pre-planned early primary states all of our honorable Democratic candidates signed a pledge not to compete in those two states. The candidates recognized that those states violated the rules and should not distract from the DNC's selected early states. Today we learn the shocking news that one of the candidates decided to throw the pledge out the window. That's right, one of the candidates decided that they no longer have to live up to the obligation they made, the promise they committed to the early states and the Democratic Party, because those states are behind him. That candidate has made a HUGE ad buy in the state of Florida reaching 6.6 million households with his ads. I understand that when a candidate is trailing in the polls in a state they do some desperate things, but to disgrace the sanctity of a signed pledge? Are pledges not part of the Politics of Hope Senator Obama?
