Atlantic magazine's most influential Americans
The Atlantic has their list of the 100 most influential figures in American history. The top 4 is pretty obvious (Lincoln, Washington, Jefferson, F.D. Roosevelt), after that it's anybody's list. Ralph Nader's entry, at number 96, offers a little wit:
He made the cars we drive safer; thirty years later, he made George W. Bush the president.
Here is the list of actual living Americans who received votes. Only three entries (Bill Gates, James D. Watson, and Ralph Nader) made the overall hundred.
