Assassinations, assassinations and «sudden» deaths of American presidents

In the United States, assassinations, assassinations and "sudden" deaths of presidents are far from uncommon. So, "suddenly" died as president: in 1841, Harrison, in 1850. Taylor, in 1923 Harding, in 1945 Roosevelt. They were assassinated as president: Lincoln in 1865, Garfield in 1881, McKinley in 1901, Kennedy in 1963. The mystical message of the Great Indian Chief Tecumseh that all the presidents elected or re-elected in the year ending at zero died or were killed in office had absolutely nothing to do with it, there were completely different reasons.
