Countries such as France or Argentina have an election system where the top two candidates proceed to a final runoff round. Historically speaking and across all (or a large number of) such countries, how often does the candidate who came second in the first round end up winning in the second round?

I'm primarily interested in top-level elections, which are listed in this Wiki article. But if there's only data for sub-national level elections, I'll accept that as well.

    It's quite probable to happen if there were three candidates in the first round, and the voter's base of place two and three dislike the winner of the first round more than each other. (Think En Marche/Socialiste versus Front National in France.)

    @ccprog True. But that's pretty obvious. How often that's the case is the question

  • @whoisit But what would that tell us? Each race is going to be different and will have its own dynamics. What really matters is the respective (un)popularities of #1 and #2 with regards to all voters in round 2. And that will differ by the circumstances so there is no "rule" to be generalized about. For example, say Le Pen in France gets 21% to say Macron's 20% (assuming he could run again). Macron would be still almost certain to win. Or was in the past. Chirac got 80% against Le Pen senior in 2002, the first time extreme right made it to round 2. Not cuz Chirac was popular. Commented Oct 25, 2023 at 1:16
  • @ItalianPhilosophers4Monica Chirac won his second term against Le Pen. For the first term, he lost in the first round against Lionel Jospin (PS), but won the second round narrowly.

It's not uncommon. Worldwide 1945-2020 according to an article in Political Studies Review:

About 30% of all second-round competitions in presidential and semi-presidential regimes result in the runner-up winning. Fifty-three of the 181 second-round elections saw the ‘surprising’ electoral comeback of the candidates who placed second in the first round. It is worth noting that a significant percentage of all the runoffs in semi-presidential and presidential regimes are won by the candidate who finished second in the first round. Comebacks at the presidential elections were reported in 34 of 73 countries included in the research.

A footnote further points out significant regional variation:

From about one-quarter in Latin America (24%), and 21.6% of cases in Africa, to about one-third in Europe (31.6%). In Asia (54%) and Oceania (50%), a full half of runoff elections have been concluded with a comeback.


I have gone through all presidential elections since 1990, in the countries that are currently part of the EU. (This means some elections took place before ascension to the EU.) In most EU countries, the president has only limited power, with the notable exeption of France. All have a separately elected head of government (minister president).

Six countries are monarchies (Belgium, Denmark, Luxemburg, Netherland, Sweden, Spain). In seven countries (Estonia, Germany, Greece, Hungary, Italy, Latvia and Malta), presidential elections are held in parliament or a special electoral body. They are extremely divers, from first-past-the-post in the third round in Germany to the extremely complicated Estonian system with multiple supermajority votes in first the parliament, then in an electoral college (that can nominate new candidates). Only one of them, Hungary, uses a runoff second round vote.


  • A: Elected in first round
  • B: Same winner in first and second/last round
  • C: Different winner in second/last round
Country A B C
Hungary 6 1 1

Fourteen countries have presidential elections by popular vote. Of them, Ireland is a special case as it uses a instant runoff system. Formally, the winner might not be picked in the second counting round, but quite probably in the last round when only two candidates remain.

Country A B C
Ireland 2 2 1

The other countries use a runoff in the second round:

Country A B C
Austria 4 0 2
Bulgaria 0 7 0
Croatia 2 4 1
Cyprus 1 4 3
Czechia¹ 0 3 0
Finland 1 4 0
France 0 5 1
Lithuania 2 2 3
Poland 1 5 1
Portugal 7 0 0
Romania 1 4 3
Slovakia² 0 3 2
Slovenia 2 4 2
Sum 21 45 18

¹Czechia elected the president in parliament until 2008. The first public vote took place in 2013.

²Slovakia elected the president in parliament until 1998. The first public vote took place in 1999.
