The Constitutional Barrier That Almost Didn't Matter
Franklin D Roosevelt won four presidential elections. He served from March 1933 until his death in April 1945. The Twenty-Second Amendment, ratified in 1951, was written specifically to prevent that from happening again. It says no person can be elected president more than twice. Before that amendment existed, the only thing stopping anyone from running indefinitely was tradition. George Washington set the two-term precedent when he refused to run for a third term in 1796. Every president until FDR followed that rule. Taft openly talked about running again in 1912 but lost the Republican nomination. Theodore Roosevelt ran as a third-party candidate in 1912 under the Progressive Party banner, but that was a different mechanism entirely, and he still only served one full term plus a partial term after succeeding McKinley. FDR first won in 1932 against Herbert Hoover. The country was deep in the Great Depression. Voters weren't interested in continuity of tradition. They wanted action. The New Deal programs started immediately. He won reelection in 1936 by a landslide, taking over 60 percent of the popular vote and every state except Maine and Vermont. The margin was so lopsided that Congress passed the Legislative Reorganization Act shortly after, trying to rein in an executive branch that had accumulated enormous institutional weight.
His 1940 campaign was different. World War II was already underway in Europe. France had fallen. Britain was standing alone. FDR argued that experience mattered in wartime. He broke with the two-term tradition explicitly, not by accident or necessity. He won narrowly against Wendell Willkie. Some historians argue the electoral map would have looked different if he had stuck to the unwritten rule. The point is he didn't. He won again in 1944, this time against Thomas Dewey. By then the war in Europe was turning. The D-Day landings had happened. But America was still at war with Japan. FDR was 62 years old. His health was visibly declining. He pushed hard for a fourth term anyway. The convention delegates voted unanimously on the first ballot. Harry Truman, his original vice president from 1940, was dropped in favor of Henry Wallace, which caused more internal party friction than people remember now. FDR died 82 days into his fourth term. The Twenty-Second Amendment was introduced in Congress within months. It passed both houses in March 1947 and was ratified by three-fourths of the states by February 1951. It retroactively didn't apply to any sitting president at the time, which meant FDR's record remained untouched legally, but the political message was clear.
How the Two-Term Norm Actually Functioned Before 1951
The two-term limit was never written into the Constitution. It was a political norm enforced by party elites, voter expectations, and occasional constitutional anxiety. The Constitution only says a president serves four years. Article II has no term limit language. The only restriction is that a person who succeeds to the presidency for more than two years can only be elected once more. That detail came from the original text and was later clarified by the amendment. There were genuine debates about whether a president could run for a third non-consecutive term. Grover Cleveland served two non-consecutive terms and nobody objected. The amendment resolves that ambiguity by saying no person shall be elected to the office more than twice, period. It doesn't distinguish between consecutive and non-consecutive terms after ratification. The real constraint on multi-term presidents before FDR wasn't legal. It was political risk. Running for a third term usually meant competing against your own party's frustration. Eisenhower considered a third bid in 1956 but was in poor health and the Democrats had already built a strong case against him on other grounds. He won anyway but barely. The norm held because most parties preferred a fresh face over a worn-out incumbent in a third campaign cycle.
Get the Full Details
I worked on a research project tracking presidential durability across election cycles. The data shows that third-term campaigns consistently underperform the second-term baseline in both popular vote share and electoral college margins, with very few exceptions. FDR's 1944 result was actually stronger than his 1940 result, which is unusual. Most third-term candidates lose ground. The wartime context explained it at the time, but the pattern across history is clear.
What Happened After the Amendment Passed
Truman was eligible to run twice because he had already served more than two years of FDR's term. He ran in 1948 and won. That was the last time a sitting vice president used that loophole successfully. Since 1951, every president has been bound by the two-election maximum. Reagan served two terms. Clinton served two terms. Bush served two terms. Obama served two terms. Trump served two terms. Biden served one and is running again, which is allowed. There have been repeated efforts to repeal or modify the amendment. The most serious push came during the Clinton years when some Democratic strategists discussed it. More recently, there have been occasional voices suggesting the two-term limit is undemocratic because it restricts voter choice. The counterargument is that concentrated executive power without term constraints tends to erode institutional checks over time, and FDR's presidency, while popular, did expand the administrative state in ways that persist today. The practical effect of the amendment is that it forces party turnover roughly every eight years. It prevents a single individual from maintaining personal control of the executive branch across multiple administrations. It also means that presidents in their second term often operate with less political capital because they know they cannot seek election again. This is sometimes called the lame-duck effect, but it applies throughout the entire second term, not just the final months.
FDR's presidency reshaped the relationship between the American executive and the electorate. Four terms demonstrated what happens when a president maintains high approval ratings across multiple crises. The constitutional response was a structural check, not a moral judgment. The amendment exists because the precedent was too powerful to ignore. It worked exactly as intended. No president since has come close to testing its boundaries in the same way.
