The City Council is set to ratify a bill that would give non-citizens the right to vote Thursday – which could fundamentally change the shape of New York City politics.

If the bill passes, it would apply only to non-citizens who are legally documented, like Dreamers and green card holders who are old enough to vote and only apply to some city elections - not state or federal ones.

It would give 800,000 people voting rights.

Mayor Bill de Blasio says that while he wouldn’t veto the bill, he's not sure if the city is legally allowed to do this without permission from the state first.

The mayor also says he's worried this might disincentivize people from becoming U.S. citizens - a concern that city councilmembers who are against the bill have echoed among others.

But people in favor of the bill say this isn't a partisan thing since it impacts so many people from so many different backgrounds. They say it will just make the city's government a better reflection of the city's people who already pay taxes.

Council Member Ydanis Rodriguez, who is a co-sponsor of the bill, says he was already in tears Wednesday when the bill was going through the committee.

News 12 is told a victory rally will be held on the City Hall steps around 11 a.m.
