Key takeaway

A second Dan Sullivan on the ballot turned a safe Republican seat into a toss-up.

The Alaska Supreme Court reinstated Dan J. Sullivan of Petersburg to the 18 August Senate primary ballot on 29 June, overturning the state Division of Elections' disqualification of him for a bad-faith filing. the Court found the good-faith test the elections director had applied appears nowhere in Alaska's constitution, statute or regulation. Dan J. Sullivan shares no family tie with Senator Dan S. Sullivan.

He now runs against Republican Senator Dan S. Sullivan and Democratic recruit Mary Peltola under Alaska's top-four ranked-choice system, in which the four leading primary candidates advance and voters rank them in the general election. Two identically named Republicans on one ballot let a voter who means the senator rank the challenger first by mistake. Under ranked-choice counting, those stray first preferences can tip a close multi-round tally.

Cook Political Report moved Alaska Senate from Lean Republican to Toss-up on 1 July, citing that siphon risk directly. A seat the party had banked on holding now turns on ballot design rather than on any shift in what voters want. Alaska's Division of Elections has not said how it will distinguish the two names in August.

Deep Analysis

In plain English

Alaska's Supreme Court put a second candidate named Dan Sullivan back on the primary ballot, running against the sitting Republican senator, who is also named Dan Sullivan. Election officials had tried to keep the newcomer off the ballot over fears voters would be confused about which one they were voting for. Alaska uses ranked-choice voting, where voters rank candidates in order of preference, but that system was not built to solve name confusion. Cook Political Report has already moved the race from favouring the incumbent to a genuine toss-up.

Deep Analysis

Root Causes

Alaska's top-four ranked-choice primary was designed to prevent vote-splitting between similar candidates by letting voters rank every option. That design assumes voters can tell the candidates apart in the first place.

When two candidates share an identical name and party label, ranking both does not resolve the underlying problem: a voter who cannot identify which Sullivan is the incumbent may rank them interchangeably, diluting the incumbent's first-choice advantage regardless of how the ballot is structured. The reinstatement exploits a gap in RCV's anti-spoiler design rather than a flaw the system was built to catch.

This Event

Two Dan Sullivans, one Alaska toss-up

A name-duplicate quirk under ranked-choice voting can shave a decisive few points from an incumbent without a single voter changing their mind.

Different Perspectives

Judge Mary Geiger Lewis, US District Court for the District of South Carolina

Lewis dismissed on standing, without prejudice, the challenge by the South Carolina NAACP and three voters with disabilities to limits on who may help voters. The limits, including a cap of five voters per assistant, stand for the 3 November Senate election.

Judge Victoria Marie Calvert, US District Court for the Northern District of Georgia

Calvert dismissed the Justice Department's suit for Georgia's unredacted voter list on 30 September, holding that the 1960 Civil Rights Act does not override state privacy law. Secretary of State Brad Raffensperger need not hand over birth dates, Social Security numbers or licence numbers.

Chad Bianco, Riverside County Sheriff

Bianco, ordered by the state supreme court on 24 September to return about 650,000 Proposition 50 ballots, called his seizure a lawful investigation. He told CalMatters he would appeal to the federal courts.

Fairshake network, through Defend American Jobs

Fairshake, the crypto-industry super PAC, has said it will spend $30 million against Sherrod Brown, and Defend American Jobs, which the Washington Times places in its network, filed $11.46 million in Ohio. The Washington Times reports that the ads do not mention cryptocurrency.

Texas PAC

The super PAC reported $61.41 million of new spending on 30 September, its two largest lines opposing James Talarico and supporting Ken Paxton. Its race total of $131.53 million is the largest outside effort in any Senate contest this week, with donors undisclosed until 15 October.

Sabato's Crystal Ball

Sabato moved three Virginia seats on 29 September, putting Jen Kiggans's 2nd District at Leans Democratic and the 1st at Toss-up. It wrote that a Democratic win in the 5th, now Leans Republican, would fit a 2006-style wave.
