New York has long had the nation’s most restrictive law concerning when voters may switch from one particular party to another. Current law does not allow anyone to switch, and vote in the primary of the new party, unless the voter makes the change in the year before the primary. State Senator Daniel Squadron (D-New York city) has introduced SB 570. It would allow voters to change parties, and vote in the primary of the new party, as long as the change was made no later than 25 days before the primary.
