March 25 was the deadline to register to vote in New York's presidential primary, and there is some evidence that registration has increased ahead of the first fully contested primary in the state since 1976. Wisconsin's April 4 vote is the only major primary between now and New York's on April 19. That means Hillary Clinton, Bernie Sanders, Donald Trump, Ted Cruz, and John Kasich may show up in the state in the next few weeks. There are two public events fundraising for Bernie Sanders in Hudson on March 30 and April 8.
