Timeline of what happened

Key dates and decisions, in the order they occurred.

  1. 2025

    Sen. Ashley Moody appointed to Senate seat

  2. August 18, 2026

    Special primary election held in Florida

Florida voters went to the polls Tuesday for a special primary election to determine the candidates for a U.S. Senate seat. The election is being held to fill the remaining two years of the term originally held by Marco Rubio, who resigned to become Secretary of State.

Republican Sen. Ashley Moody currently holds the seat, having been appointed to the position in 2025. She is seeking the Republican nomination in a contested primary. On the Democratic side, the race features former National Security Council official Alex Vindman and state Rep. Angie Nixon.

Polls in the state were scheduled to close at 7 p.m. EDT on Tuesday. The winners of these primary contests will advance to a general election to decide who will serve the final two years of the term. The source did not report the names of other candidates in the contested Republican primary.

Florida voters will notice the immediate impact in the form of a change or continuation in their representation in Washington D.C. following the general election. The scale of the financial impact is not fully detailed in the source, but the winner will oversee federal resource allocation that affects Florida’s per-household share of the national budget. A shift in representation could lead to changes in how the state interacts with federal agencies on matters such as disaster relief or infrastructure funding.

The election also sets a precedent for how the state handles mid-term vacancies following high-level executive appointments. The next steps in the process involve the certification of Tuesday's primary results, followed by the general election. The specific date for the general election and the final deadline for the term's conclusion in 2027 were not reported in the source text.
