WASHINGTON (AP) — Two opposing factions in the artificial intelligence industry square off in a Democratic primary for a U.S. House seat. New York City Mayor Zohran Mamdani tests his political clout by backing fellow democratic socialists. And President Donald Trump, after two of his chosen candidates for governor lost Republican primaries this month, ensured it won’t happen again — by endorsing both candidates in a South Carolina runoff.Those are a few of the races to watch on Tuesday as voters head to the polls for primaries in Maryland, New York, South Carolina and Utah.Manhattan House primary is a bellwether for pro-AI regulation candidatesThe crowded Democratic primary became a proxy battle between two powerful camps of the artificial intelligence industry because of one candidate: New York Assemblyman Alex Bores. Bores, a former Palantir employee who cited ethical concerns in leaving the company, pushed one of the more sweeping state-level AI regulation bills in the country. Now, Bores points to that legislation — which faced some industry pushback — as a framework for how he’d approach regulation in Congress.

So when he stepped into the race for the New York congressional district being vacated by retiring Democratic Rep. Jerry Nadler, a political group underwritten by investors in OpenAI spent more than $7 million on ads against Bores.
