I just finished writing a list of the Top 20 Satirical Candidates of All Time, which I've now added to the site. It seemed an appropriate time for it. I chose "Nobody" as the #1 satirical candidate. I thought it was an obvious choice. After all, how can Anyone top Nobody?
But also on the list are the foot powder that won an election, Pat Paulsen, Stephen Colbert, Vermin Supreme, etc.
What the list doesn't cover is mock political parties. The focus is entirely on candidates.
