The heated battle for Congressional super-delegate votes may be just about over, with Obama-backer Sen. Claire McCaskill (D-MO) saying this morning that most of the roughly 80 publicly-uncommitted members of Congress have already said where they stand in private.

"The majority of super-delegates I've talked to are committed, but it is a matter of timing," said McCaskill, predicting that her candidate would come out on top in the end.

Meanwhile, George Stephanopoulos reported this morning that the Obama campaign will roll out multiple super-delegate endorsements today, as part of a strategy to "try to get back on track" in the wake of the most recent Jeremiah Wright controversy.
