Alaska, Florida and Wyoming hold primaries Tuesday, August 18, completing another major section of the 2026 nomination calendar. For voters, the common date is where the similarity ends.

Election administration is state and local. Registration rules, party-primary access, early voting, absentee deadlines, polling hours and ballot designs differ. Voters should use their own state and local election authority—not a campaign message or national social-media post—as the final source for where and how to vote.

Alaska

Alaska voters can find official election information through the Alaska Division of Elections. The division publishes voter registration tools, polling-place information, candidate materials, absentee guidance and official results.

Alaska's election rules have changed repeatedly through ballot measures, litigation and legislation. That makes stale explainers particularly risky. Voters should confirm the exact 2026 primary format and the number of candidates who advance using the division's current voter materials before marking a ballot.

Nationally, Alaska draws attention because it has a U.S. Senate election in 2026, according to the FEC primary calendar. The state also elects its at-large U.S. House member and state offices. The correct way to follow the count is through the state's results portal and clearly attributed AP calls—not assumptions based on early returns from one region.

Alaska spans four time zones and contains communities with sharply different ballot-return logistics. Early totals may not represent the eventual electorate. A slow count is not evidence of misconduct; the relevant questions are what categories of ballots remain and what deadlines state law sets.

Florida

Florida's primary Election Day is August 18. The state registration and party-change deadline was July 20; the deadline to request that a vote-by-mail ballot be mailed was August 6; and the mandatory early-voting period runs August 8 through August 15, according to the Florida Division of Elections. Counties may offer additional early-voting days, so voters should consult their county supervisor of elections.

Florida is a closed-primary state for party nominations: voters generally must be registered with a party to vote in that party's primary. Nonpartisan contests and universal-primary situations can operate differently. The state advises voters to use its official resources and county election offices for ballot-specific questions.

Florida's official election pages also contain an easy trap for national summaries: a planned special primary may be canceled when only the necessary number of candidates qualifies. The state says a proposed August 18 special primary for state Senate District 21 will not occur, while the special general election remains scheduled for November 3. That is why a calendar date alone cannot establish that every listed contest will appear on a ballot.

Voters can start with the state's voter information portal and then follow links to their county supervisor for polling and ballot details.

Wyoming

Wyoming's primary is also August 18. The Wyoming Secretary of State's election center publishes a candidate roster, voter guide, registration information, absentee guidance and county links.

The state's ordinary registration deadline was August 3, but Wyoming permits eligible voters to register and vote at their polling place on Election Day. The state says absentee voting runs from July 21 through August 17 and that absentee ballots may be received by the county clerk until 7 p.m. on Election Day. Registered voters faced a May 13 deadline to change party affiliation for the primary, while newly registering voters could still declare an affiliation later, according to the state's 2026 key-dates document.

Wyoming has a U.S. Senate contest, an at-large House seat and state offices on the 2026 ballot. Voters should use the candidate roster and their county clerk's sample ballot to determine which contests apply to them.

How to read election night

Three rules prevent most bad conclusions on primary night.

First, a result call is not certification. AP and other news organizations may declare an apparent winner before election officials complete the canvass.

Second, the first returns are not a representative sample. Early votes, Election Day precincts and geographically remote ballots can be reported in different sequences.

Third, percentages are only as complete as the denominator. Before treating a margin as final, check the share of reporting units, outstanding-ballot information and whether the state is publishing votes counted or precincts reporting.

The safest workflow is simple: use state and county pages for voting instructions and official totals; use clearly labeled news calls for whether a race has been called; and wait for canvass and certification before calling a result final.
