Study finds Grok and GPT back opposite parties in US races

Published

Ongoing: AI Cooling

Researchers at Convovo found that Grok 4.7 recommended the Republican in 92% of answers, while GPT-6.1 Sol chose the Democrat in 97%, across nearly 500 US midterm races. The two models agreed in fewer than 10% of cases.

Convovo is a conversational AI studio led by Cornell professor Tapan Parikh. Its researchers tested the models through developer interfaces and forced them to name one candidate. In the consumer apps, ChatGPT and Grok refused to say who to vote for.

The bias held in safe seats. GPT chose the Democrat in 57 of 67 heavily Republican districts. Grok chose the Republican in 47 of 72 deep-blue districts.

The researchers also tested 30 races with web search switched off. GPT chose the Democrat in 24 and the Republican in one, and declined five. Grok refused 27 and chose the Democrat in three.

An OpenAI spokesperson said the study used developer interfaces with prompts that explicitly demand a recommendation, which does not reflect how people use ChatGPT. SpaceXAI, which makes Grok, did not respond to a request for comment. The US midterm elections are on 3 November.

Elections Hot

What you need to know

Voting in the 2026 Local Government Elections is under way at 23,696 stations, and the Electoral Commission of South Africa (IEC) reported a smooth start on 4 November. Stations opened at 7am and close at 9pm, and by 10am preliminary figures showed 3,523,691 voters had cast ballots.

There were problems: unused ballot papers were stolen from Mnyameni Secondary School near Durban, police opened a case, and the IEC relieved the station staff of duty. Some voters in Tshwane said they were turned away for wearing party shirts, but the IEC denied this and said only mayoral candidates' entourages were barred.

ANC chairperson Gwede Mantashe told members not to query the results or discredit the IEC, while the IEC said false online claims show routine procedures as fraud.

US mid-terms Heating up

Democrats won back both the US House and Senate in the midterm elections held on 3 November, according to media projections. Exit polls showed voters were angry about high prices and the direction of the country, and rebuked President Donald Trump.

Before the vote, US forces struck targets on Qeshm Island in Iran, while Republicans struggled to defend the war against Iran on the campaign trail. Iranian officials said US voters rejected the war, and Tehran stayed on high alert for possible new US strikes.

Markets reacted, with the dollar hitting a one-month low and the rand firming to around R16.55, as analysts pointed to fears of gridlock in Washington.
