Independent voters could help decide Tuesday’s congressional elections, but winner-take-all races and single-member House districts make it difficult for independent candidates to turn dispersed support into seats.
Democrats and Republicans are competing for control of the US Congress in Tuesday’s House and Senate elections. Independent voters could prove decisive, even though independent and third-party candidates win few seats, Al Jazeera said in its November 2 preview. The two major parties have dominated federal politics for generations.
Pew Research Center’s annual National Public Opinion Reference Survey found that 44 percent of US adults identify as politically independent. That measures how people describe themselves, not whether they support independent candidates. Most self-described independents lean toward a major party; those with no partisan leaning account for about 7–10 percent of the electorate.
Registration is another distinction: Florida, for example, uses “no party affiliation” for registered voters who choose not to affiliate with a party. That administrative designation differs from answering a survey question about political identity. An independent candidate has no formal party affiliation; a third-party candidate represents a party other than the Democrats or Republicans.
A single-member House district elects one representative. In a winner-take-all contest, support for losing candidates does not earn them a share of the seats. Even substantial support for a minor party can therefore fall short if its voters are spread across districts rather than concentrated in one.
Voters can reinforce that barrier by choosing a Democrat or Republican they consider more likely to win rather than an independent they prefer. Some fear a “spoiler” effect: taking votes away from a major-party candidate and helping that candidate’s rival win. Political scientist AJ Simmons said voters also fear wasting their ballot when the strongest competitors belong to the major parties.
The court denied the Trump administration’s emergency request on 2 November after lower courts rejected its bid. The administration alleges the mail ballots came from noncitizens.
Political scientist Bernard Tamas identifies money as the main obstacle for third-party candidates. He said there is little evidence that legal barriers to getting on the ballot are undermining them. Independent candidates raise little money and are less familiar to voters, he said.
Al Jazeera’s November 2 report counts one independent in the US House and two in the Senate.
Former senator Joe Manchin left the Democratic Party to become an independent in 2024. In July, he launched the Independent Leadership Council to connect independent congressional candidates with donors and campaign resources. The group has raised more than $10 million.
The council is supporting California Congressman Kevin Kiley, who left the Republican Party to seek reelection as an independent. Tuesday’s election is the immediate test for candidates like Kiley. Analysts cited by Al Jazeera say the longer-term test is whether independents can remain competitive across multiple races and election cycles, rather than attract only a protest vote.
