There is much discussion about how the 2024 US Presidential elections will play out, and media types have pushed several comparisons to prior elections, seemingly in an attempt to predict the future from the elections of the past.  Analogies are usually not perfect, but there are a few that might be instructive. Three-way presidential races, where there are viable third party candidates or independents, and races between current and former presidents, upset the balance between the two major parties and lessen the predictability of the outcomes. The “third” candidate becomes a mediating variable that is hard to analyze.  A brief review of the history of such elections sheds light on such unpredictable contests.

• The election of 1860 was a 4-way contest between Abraham Lincoln and 3 Democrats at a time that the country was seriously polarized due to sectional differences arising from the slavery issue and the states’ rights argument. Sen. Stephen A. Douglas of Illinois (against whom Lincoln ran in 1858 for the Illinois Senate seat) represented the northern Democrats, John C. Breckenridge (incumbent Vice President of the United States) drew support from the southern states, and John Bell of the newly formed Constitutional Union party gained electoral votes from the border state region. Lincoln won almost all the electoral votes in the north, the three Democrats split the rest, and Lincoln won the presidency.

• In 1892 former President Grover Cleveland, Democrat, came back to challenge incumbent Republican President Benjamin Harrison (who beat Cleveland in 1888).  In this return contest Cleveland won back the presidency, the only person in US history to have 2 unconnected terms in the White House. The third party candidate in the race, James B. Weaver, representing the Populist Party, won almost 9% of the vote and carried a few western states, which may have hurt Harrison.

• The 1912 election was the race of the 3 presidents, one past, one current and one future. Former President Theodore Roosevelt ran against his old protégé William Howard Taft and won 27% of the vote. President Taft, the incumbent Republican, ran third with only 23% of the vote and only 8 electoral votes. Socialist candidate Eugene V. Debs won about 6% of the vote. Roosevelt and Taft split the Republican vote, and New Jersey Governor Woodrow Wilson, the Democrat, won the election with only 41% of the popular vote but an electoral landslide.

• The presidential election of 1948 was famous for the biggest media faux pas in American history when the Chicago Tribune prematurely published a headline that stated: “Dewey Defeats Truman”. Incumbent President Harry S. Truman beat New York Governor and former prosecutor Thomas E. Dewey by a fairly comfortable margin in the electoral college. Truman was not that popular and the third party candidate, Dixiecrat South Carolina Governor Strom Thurmond denied Truman a sizable portion of the southern Democrat vote. After attempts to get him to drop out of the race the Democratic Convention nominated Truman, who went on to win by waging a strong campaign.

• There was a similar outcome in the 1968 presidential race but this time the Democrat split gave the election to the Republican former Vice President Richard M. Nixon. Democrat Gov. George Wallace of Alabama ran on the American Independent ticket and won 5 southern states, denying Democrat and incumbent Vice President Hubert Humphrey the electoral votes of those states and a significant portion of the popular vote.

• In 1992 independent Ross Perot, a Texas billionaire, won 19% of the vote, most of it from incumbent Vice President Republican George H.W. Bush, giving the election to Democrat Arkansas Gov. Bill Clinton. Perot scored one of the highest third party totals in US history. Ironically Bush had a national approval rate of 81% following the 1991 Gulf War, only to see his popularity dwindle to only 37 percent of the vote in the election.

The election of 2024 may be a mix of these scenarios. There is a viable third party candidate I Robert F. Kennedy, Jr, who is drawing about 10% in many polls, but not enough to be in contention for any electoral votes in the swing states. He appears to be taking more votes from Biden than Trump as we see a shift of a few points in the 5-way polling (including 2 other third party candidates), as opposed to the head-to-head data showing Trump with about a 2 point lead over Biden.

The post June 27 debate polls show a slippage in Biden’s support, most notably in the swing states, where Trump now leads outside the margin of error in 8 of 14 critical states.  Worse for Biden is that New Hampshire, Minnesota and Virginia, which have voted Democrat in recent elections, are now within the margin of error. There will be more to come with the polls following the assassination attempt on Trump.

Predicting the future from the past is always a lesson in objectivity and thought, and this election is no different.
