Looks like the Democrats are slowly moving towards supporting Feingold. Raw Story is reporting that Barbara Boxer has signed on as a co-sponsor of the censure resolution:

Sen. Barbara Boxer (D-CA) has become the third U.S. senator to back a move to censure President Bush over the warrantless wiretapping program. She joins Sen. Tom Harkin (D-IA) and Sen. Russ Feingold (D-WI)

Boxer’s office said she would support the measure.

“Senator Boxer has said she would vote for the Feingold resolution,” Boxer press secretary Natalie Ravitz told RAW STORY.

This is a good start. Perhaps some more backroom deals can take place to get more Democrats to sign on. All Democrats signing on would be great but that is highly unlikely. We know that Lieberman is pretty much a write off.
