Incumbent and establishment backed candidates face their test before voters on Thursday as they are challenged by a wave of challengers who are vowing to upend the status quo in New York.

“We're seeing a groundswell of support for a different kind of politics in New York state right now. People are really excited to see candidates like Cynthia Nixon, Jumaane Williams, the anti-IDC candidates, people who are willing to run against politics as usual. People who are activists in their own communities,” said Karen Scharff, Working Families Party co-chair.

In the race for governor, incumbent Andrew Cuomo faces actress and education advocate Cynthia Nixon in a primary. He has all the advantages: A large fundraising advantage and union endorsements, translating to a broad lead in the polls.

“He is really just not an incumbent that is threatened in any way. Not only because of his standing with the voters, but he's got this huge campaign war chest, he's got labor backing him, all of those things you'd want on the ground,” said Morgan Hook, SKD Knickberbocker vice president.

But Nixon supporters have reason to hope: They point to incumbents losing upset races, first in a Queens congressional district in June, and a Massachusetts House primary last month. They also question whether polling accurately reflects a groundswell of anti-incumbent fervor they think could help Nixon win.

“There is one section of the Democratic primary voter that is more progressive and they're demanding change, but again, when you're talking about Andrew Cuomo, we've seen statewide polls, poll after poll, that indicates he has this huge lead,” said Hook.

Meanwhile, Democrats Thursday decide between four candidates for attorney general: Leecia Eve, New York City Public Advocate Tish James, Congressman Sean Patrick Maloney and Zephyr Teachout.

“There is only one candidate in that race being able to get his message out, I'm talking about Sean Patrick Maloney,” said Hook.

Down ballot, former members of the Independent Democratic Conference all face challenges as well from candidates eager to end the status quo in state government.

Regardless of who wins Thursday, Nixon supporters contend the state Capitol will be a different place come January.

“All of the things these people are running on, they're going to bring those things to Albany, and the people who are already here are going to have to respond to that,” said Scharff.

Polls close statewide at 9 p.m.
