We are two of the most famous american presidents.
our names both have sixteen letters.
i was born in 1846, he was born in 1946.
i was elected in 1860, he was elected in 1960.
we both died on friday by gunshot to the head.
who are we?

You should really know about U.S. presidents already but you can easily walk through this with a little research.  What president was Elected in 1860? And again what president was elected in 1960? By knowing the amount of letters in their name may be helpful, however their birthday and how they died will help you narrow it down to make only 2 options left. Thank you for taking the time to read my answer.
