The cute little gal depicted at left is a zedonk -- the offspring of a zebra father and a donkey mother. She's four days old at present.
In addition to all its other flaws, overemphasis of bipartisanship (see: Unity '08, David Broder, etc) often ends up being deeply parochial. There are a lot of creatures on our planet besides donkeys and elephants. The idea that a donkey-elephant crossbreed might bring together the best things the political world has to offer is testament to the narrow horizons of one's political world.
