The answer is that several presidents had not previously held elected public office before becoming President: Zachary Taylor, U.S. Grant, William Howard Taft [although he was governor-general of the Philippines], Herbert Hoover, and Dwight Eisenhower.
This now includes Donald Trump.
President-elect Donald Trump never served in any political office, elected or appointed and was never in the military. Herbert Hoover was the only other president who did not hold elected office or serve as an officer in the military. However, Hoover was Secretary of Commerce under Harding and Coolidge.

No- Taylor never held any elected office before he was President. He never even voted.
Zachary Taylor had never voted when he ran for President.
Zachary Taylor had never even registered to vote for past elections. I am not sure that he even voted for himself.

President Obama was when he selected Biden as his running mate. Everyone who voted for Obama in the election also voted for Biden and are therefore responsible for his election as well.
