Question: Millard Fillmore was one of four presidents to serve without what traditional support?
Answer: Millard Fillmore served his entire presidency without a vice president. He’s one of only four presidents—along with John Tyler, Andrew Johnson, and Chester A. Arthur—to complete a full term without a second-in-command. At the time, the Constitution had no way to replace a vice president who died or left office. That changed with the 25th Amendment in 1967, which allows presidents to nominate a new vice president, subject to congressional approval.
