Spin Cycle

Obama secures another superdelegate on Tuesday morning -- Rep. Joe Donnelly of Indiana:

"At a time when too many Americans have lost faith in their government, Senator Obama can move us beyond the politics of stalemate and gridlock that has kept us from meeting the monumental challenges of our time: our dependence on foreign oil, a health care gap that leaves tens of millions uninsured, the steady deterioration of our manufacturing base, and an economy that is not working for working people."

More unusual: Hillary loses a pledged delegate -- one that was on her slate in Maryland, that she was entitled to from her share of the vote. He's Jack B. Johnson, the Prince George's County executive:

"I cannot in good conscience go to the convention and not support Barack. She ran a great campaign, but she fell short of the line."

Pledged delegates are generally loyalists to whatever candidate has put them on his/her slate, but technically they aren't legally bound to vote for that candidate. In Johnson's case, though -- he had been an Obama supporter, then switched to Clinton. Now, he's switching back. So, maybe it's not as odd as it seems.
