"Tipping-point state" is used to analyze the median state of a United States presidential election. In a list of states ordered by decreasing margin of victory for the winning candidate, the tipping point state is the first state where the combined electoral votes of all states up to that point in the list give the winning candidate a majority in the Electoral College.

The idea of a "tipping-point state" can be interpreted as suggesting a counterfactual, on the assumption that outcomes in different states are strongly correlated: if the nation-wide vote margin were shifted, but the order of states by vote margin were unchanged, the tipping-point state would be the state or states in which a change in the state winner would result in a change in the national winner. The term may also refer to the state that would give the second-place candidate a majority of the electoral vote when all states are arranged in order of their vote margins; this is typically, but not always, the same state as in the primary definition.

Since the number of electors was set to 538 for the 1964 United States presidential election, 270 electoral votes have been required to win the Electoral College. In some elections, there can be multiple tipping-point states for different candidates: if no candidate receives 270 electoral votes, a contingent election is required in the United States House of Representatives. For example, in the 2020 United States presidential election, if Donald Trump had won Wisconsin, Arizona and Georgia, the electoral college would have been tied 269–269: thus, Wisconsin was the tipping-point state for a Biden victory, whereas Pennsylvania, the next-closest, was the tipping-point state for a Trump victory.

Origin

The concept of a tipping-point state was popularized by FiveThirtyEight's Nate Silver.{{cite news |last1=Katz |first1=Josh |title=Florida Is Most Likely to Be the Election 'Tipping Point' |url=https://www.nytimes.com/2016/08/03/upshot/florida-is-most-likely-to-be-the-election-tipping-point.html |access-date=26 February 2019 |work=The New York Times |date=2 August 2016}} FiveThirtyEight regularly predicts which state will be the tipping-point state in a given presidential election through the site's "Tipping Point Index". Past predictions of tipping-point states include either Michigan or Ohio in the 2008 election,{{cite magazine |last1=Silver |first1=Nate |title=The Tipping-Point States |url=https://newrepublic.com/article/63505/the-tipping-point-states |access-date=26 February 2019 |magazine=The New Republic |date=22 July 2008}} Ohio in the 2012 election,{{cite news |last1=LoGiurato |first1=Brett |title=Mitt Romney Is On The Verge Of A Major Electoral Map Comeback |url=https://www.businessinsider.com/mitt-romney-electoral-map-college-swing-states-ohio-florida-obama-2012-10 |access-date=26 February 2019 |work=Business Insider |date=11 October 2012}} Florida in the 2016 election,{{cite web |last1=Hickey |first1=Walt |title=Which Tipping-Point States Favor Trump? |url=https://fivethirtyeight.com/features/which-tipping-point-states-favor-trump/ |website=FiveThirtyEight |access-date=26 February 2019 |date=2 November 2016}} and Pennsylvania in the 2020 election.{{cite web |title=The winding path to victory |url=https://projects.fivethirtyeight.com/2020-election-forecast/#ec-margins |website=FiveThirtyEight |access-date=1 November 2020 |date=1 November 2020 |archive-url=https://web.archive.org/web/20201101172256/https://projects.fivethirtyeight.com/2020-election-forecast/ |archive-date=1 November 2020}}

Because a majority of the electoral vote is required in order to clinch the presidential election in the Electoral College,{{efn|If no individual wins a majority of the electoral vote, the U.S. House of Representatives determines the winner in a contingent election.}} the tipping-point state for the first-place finisher and the second-place finisher may differ if more than two candidates received electoral votes, or if a shift in the states would leave the electoral vote tied. Tipping-point states may also differ depending on the disposition of faithless electors, on the assumption that certain faithless electors may have chosen to give their vote to the candidate they had pledged to vote for if their vote would have given that candidate a majority of the vote. Because electoral votes are awarded to winners of Washington, D.C. and certain congressional districts,{{efn|Nebraska and Maine award two electoral votes to the statewide winner and award the remainder of their electoral votes based on the winner of each congressional district. Since the 1832 presidential election, the vast majority of states have awarded all of their respective electoral votes to the statewide winner, but various methods have been used historically. In some cases, such as the 1860 United States presidential election in New York, parties have formed fusion tickets in which they agreed to split a state's electoral vote if they won the state.}} it is possible for the tipping-point to be something other than a state.

The tipping-point state is not related to the chronological order in which state-by-state election results are reported, either by media outlets or by state officials. Rather, the media uses decision desks to project the apparent winners of each state before all the votes are counted, and will announce a state that they project will give a candidate enough electoral votes to become the apparent presidential winner. The tipping-point state can only be determined after all the votes in each state are counted and certified, and thus all the vote margins are accurate. For example, the projection of Joe Biden to have won the state of Pennsylvania in the 2020 election made him the projected winner of the electoral college, but for Biden the tipping point state of the 2020 election was Wisconsin, which was called for him three days prior.

Example: 2012 presidential election

=Obama victory tipping point state=

In the 2012 presidential election, Barack Obama defeated Mitt Romney in the electoral vote, taking 332 electoral votes compared to 206 for Romney. As with all presidential elections since the 1964 election, 270 electoral votes were needed to win a majority in the Electoral College. Obama would still have won a majority of the electoral vote even if he did not win Virginia, Ohio, and Florida, the three states in which he had his smallest margin of victory. However, if Obama had lost those three states as well as Colorado (where he recorded his fourth-smallest margin of victory), he would not have won a majority of the Electoral College. Thus, Colorado was the tipping point state for an Obama victory in 2012.
