I am one of the millions that won't be able to vote for my candidate of choice in the primary because I was registered as an Independent, and you had to switch party affiliation 8 months ago.
You'd think a state like NY would be less restrictive. 8 freaking months before than election?!?

As the surprisingly pivotal New York presidential primary draws closer, an upswell of voters have begun to organize against the State's closed primary system, which excludes 3.2 million independent voters, or about 27% of the voting public. For comparison, there are only 2.7 million registered Republicans state-wide.
A State bill introduced in late March would bust the closed primary wide open, permitting all registered New Yorkers to vote. Social media has been peppered with links to the legislation in recent days ("This is YUUUUGGGGEEE!!!"

, and some have wondered if it could be passed in time for next Tuesday—a possibility that the bill's sponsor, Independent Assemblyman Fred Thiele, says is a very long shot.
"I don't have any illusions that we're going to get this done by next Tuesday," Thiele told us this afternoon. "There's obviously a lot of resistance in Albany, which is biased towards the two major parties. But I hope we can make 2016 the last closed primary in New York."
"It was amazing how many telephone calls and e-mails I got in the last few months complaining about not being able to participate," he added. "From unaffiliated voters, and also those who wanted to change their party to vote in this election. If you wanted to change your party you had to do that last October, when people weren't even thinking about it."
The closed primary, combined with New York's extremely early change-of-party deadline (October 9th, the earliest in the country), is likely to have an outsized impact on Donald Trump and Bernie Sanders supporters—polar opposites in many ways, but similar in that they're poised to buck the establishment with their votes, and are more likely to be unaffiliated. Bernie's camp was so concerned about the votes it might lose in New York, that the campaign released a PSA ahead of the October deadline, urging the non-affiliated to register as Democrats. (Unregistered voters had until March 25th to file their registrations.)
