# Two-Round System
Who / What
The **two-round system** is a single-winner electoral voting method designed to ensure a candidate secures the majority support of voters. It operates through two rounds: in the first round, voters rank candidates by preference; the top two candidates advance to a second round where only their names appear on ballots. The winner is determined by the candidate with the most votes in this runoff.

Background & History
The two-round system has roots in historical electoral traditions, particularly in France, where it was formalized during the French Revolution as part of the *système électoral* to prevent fraud and ensure representative legitimacy. Its origins trace back to ancient Greek and Roman systems, though modern iterations gained prominence in the 19th century with reforms aimed at reducing vote manipulation. Key milestones include its adoption in France’s 1848 Constitution and later in countries like Belgium, Portugal, and Switzerland, where it balances democratic inclusivity with electoral integrity.

Why Notable
The two-round system is notable for its ability to mitigate the risks of a "spoiler effect" by eliminating low-popularity candidates early. It prioritizes broad-based support over narrow plurality, reducing the likelihood of contested elections through runoff voting. Academically and politically, it remains a subject of debate due to its potential to increase voter turnout in second rounds while occasionally prolonging campaigns.

In the News
Currently, the two-round system garners attention in discussions about electoral reform, particularly in countries like France (where it is mandatory for presidential elections) and Australia (which uses a modified version). Recent debates highlight its effectiveness in reducing polarization by ensuring candidates must appeal to diverse voter bases. Advocates emphasize its role in fostering stable governments, while critics argue it can extend election timelines.
