X-poster from reddit/Kossacks for Sanders: There are a lot of problems already reported with voting, which began at 6am, but please pass this all along to NY voters if you hear of any problems:

Sanders’ Campaign HQ in NY:

IF YOU HAVE ANY SERIOUS ISSUES CALL THE CAMPAIGN VOTER HOTLINE 347-379-4298

If the poll workers are unable to find you in their book, have them check other books to see if you are listed. If they are unable to find your registration call this number 1.866.868.3692 (1.866.VOTE-NYC FREE) and have them confirm polling location and which book you are listed in and in many cases that will resolve the issue so you can cast another ballot. You may have to go to another polling location if you are at the incorrect one. Only accept an affidavit ballot as a last resort, but do everything you can to get a regular ballot!

If you have any questions about voting in New York you may contact your state elections office for more information. New York Elections Office -- Phone: (518) 474-6220

Other info from various sources about what to do in NY if you have voting problems: New York State Attorney General Eric T. Schneiderman has a telephone hotline set up at 800-771-7755 FREE for anyone encountering problems at the polls.

U.S. Attorney Preet Bharara's office will also be operating a voter complaint hotline, at 212-637-0840.

Please call these numbers. Also tell them that there are reports of people not being found in their polling places poll books, but they looked in the other district books and were found there. Note: people are reporting good luck contacting the AG's office in some cases today.

NYers who face problems at the polls, have the right to go to the BOE (Board of Elections) office on election day to see a judge who can grant them the right to vote in the NY primaries:

Finally, and IMPORTANTLY, Election Justice filed an emergency 9 am court hearing to deal with voter registration changes in NY State that were potentially disenfranchising to a huge number of voters (Mayor DeBlasio has expressed serious concern):

They recommend the following (to the best of my ability to understand this clearly):

If you believe your registration was switched and you are really a Democrat, vote on affidavit and sign section asserting that you are.

If you are an independent who just wants to vote if the primary happens to be opened by the lawsuit, vote by affidavit but DO NOT SIGN that section.

"We are encouraging all independent and disenfranchised voters to VOTE tomorrow by provisional ballot," Nelson said. "They should tell poll workers that there is a motion pending in Federal District Court to declare the Primary open, and they are casting their vote in the expectation of a favorable ruling by the judge tomorrow." (Shyla Nelson, spokeswoman EJUSA)

WHEN SOMETHING JUST SEEMS WRONG: 1.) Get the poll workers' name; 2.) Record it; and 3.) Upload it TO SOCIAL MEDIA AND TO THAT THREAD. You may also wish to use it to go before a NY Judge today to "sue" to vote (as above). You may also wish to present it to the BOE (Board of Elections). The NY ACLU is another resource you may wish to pursue if you have exhausted all other channels, as they also help with voting rights.

Feel free to bookmark this link and pass it along, on Reddit, on FB, on Twitter, and anywhere you hear of problems. I have been compiling this information for a few hours and will update it if anything new emerges.
