Footnotes:*1 Alexis Herman served as the first African American Secretary of Labor under Bill Clinton
*2 Allan Katz, though an Obama endorser, is from Florida and therefore may be inclined to seat Florida's delegation.
*3 Jaime Gonzalez Jr. was undeclared until just a few days ago. This could be indicative of how the Rules and Bylaws Committee will rule on the matter come May 31.
*4 Mark Brewer, though undeclared, is from Michigan and therefore may be inclined to seat Michigan's delegation.
*5 Ralph Dawson is the only undeclared New York Super Delegate. All other New York Super Delegates have endorsed Senator Clinton. Ralph Dawson is the member of the Rules and Bylaws Committee who initally introduced the ruling that stripped Florida and Michigan of their delegates.
