Which presidents never had a vice-president?

Answer 1

John Tyler, Fillmore, Andrew Johnson, and Chester Arthur were vice-presidents who moved up to president when the president died. In those days, a vacant vice-presidency was not filled until the next presidential election, so these men had no vice-president and were not re-elected as president so they never had a vice-president. ( Theodore Roosevelt, Calvin Coolidge ,Harry Truman and Lyndon Johnson also moved up to president from vice-president and so lacked a vice-president for their first term,but all were elected to a second term and had a vice-president then. )

Nowaday there is a process for getting a new vice-president if the President dies.
