i would tend to think that means its not true, and the elected in a 0 year thing is just a coincidence. BESIDES WHICH, thomas jefferson was elected in 1800, and did not die in office. teddy roosevelt was elected in 1900 and didn't die in office either. the assasination attempt on him occured after he left the presidency, when he was attempting to run for president again later.

there are a lot of freaky similarities in the information involving kennedy and lincoln, but some of it are stretched truths... and some of it are just the author reaching for information, like all of the points after the "Now hang on to your seat."
