📂 In-Depth Analysis: Chile’s Presidential Runoff Sets Stage for Far‑Right José Antonio Kast’s Ascendancy

The “Wikipedia” Context

Chile’s presidential election system, codified in the 1980 Constitution and refined after the 1989 democratic transition, uses a two‑round (runoff) mechanism when no candidate exceeds 50 % of votes in the first round.This design was intended to ensure a majority‑supported president while discouraging extremist fragmentation. As the 1990s Chile has held runoffs in 1999, 2005, 2013, and most recently in 2021.

The 2021 election was a watershed moment. The left‑leaning coalition Apruebo Dignidad rallied behind Gabriel Boric, a 35‑year‑old student leader, while the right coalesced around José Antonio Kast, a former congressman and the face of the emergent “republican” wing of Chilean conservatism. Kast had previously run in 2017 under the Chile Vamos banner, finishing fifth, but his 2021 campaign gained momentum by uniting traditional right parties (UDI, RN) and new far‑right forces (Republican Party, Christian Conservative Party).

Although Boric won the runoff with 55.9 % of the vote, the narrow margin-44.1 % for Kast-demonstrated the durability of a far‑right electorate. Kast’s post‑runoff role has become that of a vocal opposition leader, shaping legislative debates on public security, immigration, and constitutional reform. His ascendancy is also reflected in the rapid growth of the Republican Party, which in 2023 became the third‑largest force in the Chamber of Deputies.

Understanding the backdrop of Kast’s rise requires a look at three layers: (1) the evolution of Chile’s runoff system, (2) the fragmentation and re‑consolidation of the right after the 2019 social outcry, and (3) Kast’s personal political trajectory-from a libertarian‑conservative congressional career to the founder of a nationalist‑populist party.
