Patronus: Donkey
Here's why this is their Patronus: Donkeys can have a sweet and rather gentle desposition at first but also tend to mess everything up in the end, and are often used for comical elements within contemporary culture. Also, for some political humour, a donkey voter (http://en.wikipedia.org/wiki/Donkey_vote) is someone who votes for candidates based solely upon the order they are listed on the ballot paper, which is probably how Bush must have been elected in the first place. :P
