Hello and welcome to the US politics live blog.

Today is the state primary elections in New York, Maryland and Utah. Here are some of the races to watch:

New York state has more than twice as many registered Democrats than Republicans as of 2025 – but with the success of the progressive New York city mayor Zohran Mamdani, the question now is how blue can this blue state go.

Mamdani has thrown his support behind three congressional candidates who are challenging incumbents or incumbent-backed candidates supported by the Democratic establishment: former city comptroller Brad Lander who is up against two-term incumbent Democrat Dan Goldman in NY-10, political newcomer Darializa Avila Chevalier who is challenging incumbent Democrat Adriano Espaillat in NY-13, and Claire Valdez who is facing off against Brooklyn borough president Antonio Reynoso – the handpicked successor of Nydia Velázquez, the first Puerto Rican woman to serve in Congress who is considered a progressive giant of New York City politics – in NY-7.

Elsewhere in New York, AI-focused Super Pacs have been pouring money into a single Manhattan race: the Democratic congressional primary in the district of NY-12.

That money has primarily been going toward taking down Democratic assembly member Alex Bores, who a year ago had sponsored the Raise Act, the second-ever US state law requiring major AI developers to publish public safety plans.

Challenging Bores for the Democratic nomination to represent New York’s 12th district in the House of Representatives is Jack Schlossberg, the very online grandson of John F Kennedy, and George Conway, the Republican turned vocal Trump critic.
