as gathered from different sources by Demconwatch the most authoritative source on delegate matters:
http://demconwatch.blogspot.com/2008/01/superdelegate-list.htmlhttp://www.examiner.com/a-1326716~D_C__councilman_no_longer_member_of_Clinton_camp.htmlWASHINGTON (Map, News) - A D.C. Council member and unpledged Democratic delegate has withdrawn his prominent public support for Sen. Hillary Clinton, preferring instead to be listed as undecided in the race for the nomination.
Ward 5 D.C. Councilman Harry Thomas Jr. was elected last week by the D.C. Democratic State Committee as a delegate to the national convention. Thomas, who had previously endorsed Clinton, was listed as a Clinton backer on a delegate spreadsheet circulated Monday by the committee.
But by the end of the day, the party had retracted that announcement, and Thomas was switched to simply “unpledged.”
Yesterday Clinton had broken a long period of no new Super Delegate news with the endorsement of DNC Super Delegate from Arkansas
http://www2.arkansasonline.com/news/2008/apr/07/clinton-picks-superdelegate-arkansas/Land Commissioner Mark Wilcox, who was selected last month as the Arkansas Democratic Party’s last remaining superdelegate to the national convention, said Monday he’s supporting the New York senator.
“I voted for her in the (primary) election and support her and that’s how at this time I feel I’m going to vote. ... At this time, I’m supporting her,” Wilcox told The Associated Press
Superdelegates are free to change their minds before the convention. Wilcox said he’s been reluctant to disclose who he is supporting because he doesn’t know what could change before the party’s convention, which will be held Aug. 25-28.
“Who knows what the convention is going to be? We all could support somebody else if it changes, like if she pulls out, we’ll have to support somebody else,” Wilcox said, who added that he could not think of a scenario where he’d change his mind short of Clinton exiting the race
