William Henry Harrison for the US. He was the one who pissed off the Native Americans in the mid-west and, upon being elected president, died in office 30 days later. He was also supposedly cursed by one of the Natives he had murdered (supposedly every president elected in a year ending in 0 would die in office). It's probably something that was made up in light of the fact that it actually happened. Harrison was elected in 1840, Lincoln in 1860, Garfield in 1880, McKinley in 1900, Harding in 1920, Roosevelt in 1940 and Kennedy in 1960. I could see someone having some fun and writing that into his bio if a mod were to be made.
