You wait ages for some decent political goatery and then three items turn up all at once!
1. The following four US presidents all had pet goats: Abraham Lincoln, Rutherford B. Hayes, Benjamin Harrison, Harry S. Truman. In no case, however, was the goat their only pet and only one of these presidents had a pet opossum. A full list of presidential pets is available here.
2. Did Karl Marx employ a goat-related insult to cast aspersions on Albanians? Find out here.
3. Finally, I'm not sure what to make of this, but it seems genuine.
