Here's a full listing of where Obama and Clinton's Senate colleagues are. And although Russ Feingold admitted to voting for Obama in his state's primary, he's still listed as "uncommitted."
http://firstread.msnbc.msn.com/archive/2008/03/31/844144.aspxWith the endorsement by Sen. Amy Klobuchar (D-Minn.) for Obama, we decided to take a look at who each Democratic senator is backing. Obama, it turns out, leads Clinton, 14-12. Twenty senators are uncommitted. A couple of notes... excluded from the list is the Florida-Michigan contingent of senators: Debbie Stabenow, of Michigan, who is backing Clinton; Carl Levin, of Michigan, who is uncommitted; and Bill Nelson, of Florida, who has endorsed Clinton. Also excluded are senators, who caucus with Democrats, but do not have a vote at convention: Bernie Sanders (I-VT-Uncommitted) and Joe Lieberman (I/D-CT-McCain). Lieberman was stripped of his superdelegate status when he endorsed McCain.
