While this is probably old news for Americans, it's certainly one the strangest stories I've come across in quite a while -
Tucumseh's Curse

"The term Tecumseh's curse or zero year curse is sometimes used to describe a chain of events that began with the death of United States President William Henry Harrison from pneumonia. Commonly attributed to Indian chief Tecumseh (and sometimes to his brother Tenskwatawa, aka The Prophet, who was defeated in the Battle of Tippecanoe by Harrison), the "curse" is said to have proclaimed the death of all presidents elected every 20 years.

Victims of the "curse"

Indeed, all American presidents elected in a year divisible by 20 between 1840 and 1960 died in office:

1840 - William Henry Harrison, died of pneumonia in 1841
1860 - Abraham Lincoln, assassinated in 1865
1880 - James Garfield, assassinated in 1881
1900 - William McKinley, assassinated in 1901
1920 - Warren G. Harding, died of heart attack in 1923.
1940 - Franklin D. Roosevelt, died of cerebral hemorrhage in 1945
1960 - John F. Kennedy, assassinated in 1963."

Ronald Reagan, elected in 1980, apparently missed the "curse" by an inch - the distance an assassin's bullet missed his heart. And, of course, the article ends with speculation about the fate of the current President, elected (?) in 2000.

Well! Here I was all ready to order one of these this morning, (a "Days Left in Office" countdown keychain :~) but now I think I'll save my pennies and leave it all up to Tucumseh instead! Unless ... unless ... the curse might not cover rigged elections ...
