The Short Answer: Yes, and It's a Big Deal
Yes, Georgia law requires a candidate to receive a majority of the vote—that is, 50% plus one—to win a primary, general, or special election for a federal office like the U.S. Senate or House of Representatives. This applies to statewide offices as well. This makes Georgia stand out. Most states use a 'plurality' system, where the candidate with the most votes wins, even if they fall short of 50%. For example, in a three-way race in a plurality state, a candidate could win with just 40% of the vote. In Georgia, that same 40% would send the top two finishers to a second, head-to-head contest called a runoff. This single rule is why Georgia has become synonymous with extended election cycles that can keep the entire country in suspense.
How It Works: The Runoff System
When no
candidate breaks the 50% threshold on Election Day, the race isn’t over. The top two vote-getters, regardless of their party affiliation in a special election, advance to a runoff election held four weeks later. This second election is a clean slate. It’s a direct, two-person contest where one candidate is guaranteed to win a majority. Campaigns must re-energize their bases, raise more money, and get voters back to the polls for a second time. For voters, it means anyone who is registered can participate in the runoff, even if they didn't vote in the initial general election. This extra round of voting frequently decides not just who represents Georgia, but has recently determined the balance of power in the U.S. Senate.
A Rule with a Controversial History
Georgia's majority-win requirement isn't just a procedural quirk; it has deep and controversial roots. The system was implemented in the 1960s, a period of intense struggle over civil rights. It replaced the state's 'county unit system', a method that gave disproportionate power to rural, white counties and was struck down by the Supreme Court in 1963 for violating the 'one person, one vote' principle. In response, state legislator and avowed segregationist Denmark Groover proposed the majority-win and runoff system. Historians and legal experts note the intent was to dilute the influence of Black voters, who might coalesce around a single candidate who could win a plurality in a crowded field. By forcing a runoff, the system was designed to ensure that white voters could unite behind a single candidate in the second round, maintaining control.
Modern Impact: Deciding Control of the Senate
In recent years, this rule has had a profound national impact. The most dramatic examples came after the 2020 election, when both of Georgia's U.S. Senate seats simultaneously went to runoff elections held in January 2021. Neither Republican Senator David Perdue nor appointed Senator Kelly Loeffler secured a majority against their Democratic challengers, Jon Ossoff and Raphael Warnock, respectively. The outcome of those two races determined which party would control the Senate, and Democrats won both, flipping the chamber. The scenario repeated itself in 2022, when the race between Senator Raphael Warnock and challenger Herschel Walker again proceeded to a December runoff, which Warnock won to secure a full term. These high-stakes contests transform Georgia into the center of the American political universe for weeks, drawing massive national attention and hundreds of millions in campaign spending.
