Sanders Folks Upset About Registration Rules in NY

[Princess Turandot]

17. If an already registered voter changed their party affiliation after 10/9/2015....

they cannot vote in the Republican or Democratic primary on 4/19, as you said. And, according to the NYS Board of Elections website, the party affiliation for these already registered voters who missed the deadline is not changed in the actual voter roles until after the next General Election:

Change of Party Enrollment

The voter registration form should be used to change your party enrollment from one party to another or to enroll for the first time in a party. A change of enrollment received no later than 25 days before the general election shall be deposited in a sealed enrollment box and opened the first Tuesday following that general election and entered in the voter's registration record.

That makes sense, of course. But that may be the cause of some of these reports of 'problems'. People who changed parties in 1/2016 will not see that change on their web record because by law it has not yet gone into effect.

I found my registration to be perfectly correct! Of course, I've been a registered Democrat in NYC since I turned 18, quite some time ago. (My first vote was by absentee ballot, as I was away at school.)
