President Trump is ramping up his attacks on one of the GOP's newest targets, New York City's progressive mayoral candidate Zohran Mamdani.

The president, who has a history of spewing sometimes vile insults at rivals, has in recent days escalated his attacks against the 33-year-old self-described democratic socialist. Trump has threatened to arrest Mamdani, to deport him and even to take over the country’s largest city if he wins the general election in November.

It's one thing when the president relies on name-calling when targeting a perceived political foe. Talk about arrests is qualitatively different.
