Reply #9: He has not. From Govtrack.us:

Dennis Kucinich has sponsored 107 bills since Jan 7, 1997 of which 102 haven't made it out of committee and 4 were successfully enacted. (The count of enacted bills considers only bills actually sponsored by Kucinich and companion bills identified by CRS that were themselves enacted, but not if they were incorporated into other bills, as that information is not readily available.)

When not bashing the administration, typical Kucinich bills include:

"Proclaiming Casimir Pulaski to be an honorary citizen of the United States posthumously" and
"To designate the facility of the United States Postal Service located at 13301 Smith Road in Cleveland, Ohio, as the "David John Donafee Post Office Building".
