Hillary Clinton drank bubble tea in Queens, played dominoes in Harlem, and rode the subway in the Bronx. Bill Clinton barnstormed Upstate, hitting as many as four cities in a single day.

In the three weeks leading up to the high-stakes April 19 New York primary, the Clintons campaigned in New York their way – the Big Dog glad-handing across the state and speaking at Baptist churches in the city, the former senator methodically touching all her bases, appearing with every elected official who could help deliver a demographic and drilling down deep on local issues across the state.

On the eve of New York’s critical Democratic primary Tuesday, that nose-to-the-grindstone approach in Clinton’s adopted home state appears to have halted Bernie Sanders in his tracks. After rolling up eight wins in the last nine contests, Sanders trails by double-digits in nearly every public poll in New York.
