Dozens of New York voters are suing the state, saying that their voter registration changed without their input, costing them the ability to vote in Tuesday's primary. The lawsuit, filed this afternoon in Long Island federal court by the group Election Justice USA, argues that the voters' alleged registration changes deny them equal protection under the constitution, and demands a blanket order allowing "tens of thousands" of potential plaintiffs to vote in tomorrow's presidential primary.

"Plaintiffs are in imminent harm of losing their right to vote," the suit reads. "They have beseeched the various Boards of Elections without result. Nothing can save their right to vote save an order from this Court."

New York's primaries are closed, meaning only members of a given party can vote in that party's primary, and the deadline to change parties is more than six months before Primary Day, the earliest in the country. Those who signed onto the lawsuit say that their paperwork was in order, and in many cases they had voted repeatedly in Democratic primaries from the same address, but that recent checks of their voter registrations revealed that their party had been changed or could not be found at all. The accounts echo online reports of other spurned would-be voters.

"We were seeing an alarming number of voter affiliations changed without people's knowledge or consent, people who were registered listed as not registered," said Shyla Nelson, a spokeswoman for Election Justice USA.
