And I remember seeing similar things about Clinton, especially stuff playing on the hillbilly theme. I ask this rhetorically, but why is any criticism of Obama "racism"? Presidents have been pilloried since Day 1. It's part of the territory. This one though, anything less than fawning adulation is "racism".
The only improvement I would suggest for that parade float is to add a crescent moon. That would be funny two different ways. Which is exactly why the suggestion of Das Kapital was perfect as a new name for Washington.
