In 2001, an appeals court ruled that New Jersey's practice of not allowing anyone to register to vote as anything other than Democrat, Republican, or Independent was unconstitutional. This was the result of a lawsuit brought by a coalition of political parties, including the NJ Libertarian Party.
Since then the number of registered libertarians has been steadily growing. The 2018 numbers show 11,040 registered Libertarians. This is a 32.9% growth from the prior year. This year we have grown once again to 8,309 registered Libertarians. We have 4.8 times as many registered libertarians now than we did 5 years ago,
Help us to keep this momentum! If you are not a party member consider joining the party. If you are not registered as a libertarian please consider changing your voter registration declaration.
