HARRISBURG, Pa. - A state court knocked Ralph Nader (news - web sites) off Pennsylvania's presidential ballot on Wednesday, citing thousands of fradulent signatures including "Mickey Mouse" and "Fred Flintstone." Describing the petitions as "rife with forgeries," Commonwealth Court President Judge James Gardner Colins said that fewer than 19,000 of the more than 51,000 signatures that Nader's supporters submitted were valid. Nader needed at least 25,697 to be listed on the ballot as an independent candidate.
