Two stories from opposite sides of the globe have huge political implications today. First, in New York City, outsider candidate Zohran Mamdani pulled off a historic upset, defeating former Gov. Andrew Cuomo in the Democratic primary for mayor. The seismic victory is sending shockwaves throughout American politics, with center-left Democrats gritting their teeth, progressives in a triumphant mood and Republicans lapping it all up. Across the Atlantic Ocean, President Donald Trump is at the NATO Summit at The Hague today, where he’s expected to address the ongoing fallout from the U.S. strike on Iran and the fragile ceasefire between it and Israel. POLITICO White House reporter Megan Messerly joins Playbook author Jack Blanchard to unpack all that and more.
