As noted above, I will be traveling to Latin America in a few days. This article identifies some of the trends in Latin America about which one can be sad. It quotes Juan Peron of Argentina as saying "when one enters politics, one throws his honor to the dogs."
On the other hand, I particularly enjoyed the wisecrack: "Legislators and diapers need to be changed frequently, for the same reason." That is perhaps the best argument for term limits I've ever heard.
