New York's primaries feature Mamdani backing far-left candidates against Democratic incumbents, while South Carolina holds a governor runoff with Trump endorsing both candidates.

• New York Mayor Zohran Mamdani is supporting far-left Democratic Socialists of America candidates against mainstream Democratic incumbents in congressional races.
• Mamdani's endorsements may conflict with Democratic Minority Leader Hakeem Jeffries, who aims to protect Democratic incumbents and regain House majority.
• South Carolina voters will choose between two Republican candidates for governor, with Trump endorsing both after initially supporting one.
