Good advice is worth repeating: ahead of tomorrow’s general election, New York City voters should check their poll sites before going to vote. 

That recommendation is more valuable than ever this year because roughly one out of every five poll site has been changed since last November. That means more than 300,000 registered voters have been assigned to a different polling location for Tuesday's election than the one they had for last year's presidential contest, according to an analysis by the WNYC Data News team. 

Just before last September’s primary, WNYC reported that 20 percent of the city’s poll sites had changed since 2016, representing more than 200,000 eligible primary voters. The increase comes primarily because the general election is open to unaffiliated voters and more Republicans, most of whom did not have a contested race in during the primary election.

Here are some other details:

Will there be signs notifying voters of poll site changes?

Yes, but not thanks to the city Board of Elections. The good government group Common Cause and NYC Votes, the voter outreach arm of the New York City Campaign Finance Board, will be posting signs at some poll sites that are no longer in use.

The city Board of Elections refuses to comply with a local law that would require it to post these notices. Following the primary, City Councilman Dan Garodnick complained the elections board was not adhering to law. Last week, Garodnick rallied with good government groups to bring attention to the issue of poll site changes.

"I’m sorry — the Board of Elections does not have the right to pick and choose which laws it is going to follow," Garodnick said. "And the Board of Elections is choosing to ignore a law that would help voters know when their poll site is moved."

The board’s stated position is that the City Council does not have jurisdiction to tell it what to do.

What about LeFrak City?

Before the primary, the Board of Elections announced it was moving a poll site that's been at located at the huge middle-class apartment complex in Corona, Queens, for decades to two locations far away from the complex.

Board officials insisted they were moving the site to make voting locations more accessible to the disabled. But tenants at the site protested and eventually went to court. Their lawyer said that the move would have disenfranchised thousands of minority voters who would have had to travel up to a mile to the new poll sites.

But then, last week, a judge ruled the board's decision to move the location was "irrational, arbitrary and capricious," adding that the board was misinterpreting the conclusions of its own disability access consultant.

Ultimately, the court ordered that the poll site needed to be restored to the exact spot where LeFrak City voters have been casting their ballots for years, with one small exception. The poll site originally accommodated five election districts. Only four districts are returning to LeFrak City. The fifth remains at its new location outside of the complex.
