New York House primaries test Mamdani's influence, and more races to watch in South Carolina, Maryland, Utah

Key Points:

• Four states—New York, South Carolina, Utah, and Maryland—are holding primaries on Tuesday, featuring key congressional and gubernatorial races with significant political implications.
• In New York, several high-profile Democratic primaries are underway, including contests in the 10th, 7th, 13th, 12th, 17th, and 21st districts, with progressive and democratic socialist factions competing for influence; endorsements from figures like Mayor Zohran Mamdani, Gov. Kathy Hochul, and national politicians are shaping these races.
• South Carolina's Republican gubernatorial primary has advanced to a runoff between Lt. Gov. Pamela Evette and Attorney General Alan Wilson after no candidate secured a majority; former President Trump has controversially endorsed both candidates, reflecting shifting dynamics in the GOP.
• Utah's 1st Congressional District Democratic primary is notable due to newly redrawn maps favoring Democrats, with former Rep. Ben McAdams among four candidates vying to flip a traditionally Republican seat.
• Maryland features a crowded Democratic primary for the 5th Congressional District seat left open by the retirement of Rep. Steny Hoyer, with prominent endorsements for candidates Adrian Boafo and Harry Dunn, alongside a GOP primary for governor challenging incumbent Wes Moore.
