While the contours of the Democratic race in NY look similar to those upsets, Nixon, best known for her Emmy-winning role on HBO's "Sex and the City", has steadily trailed Cuomo by 30 points or more in opinion polls.
The endorsement comes a day before Democratic voters in NY vote to decide whether to give Cuomo a shot at a third term in the governor's mansion. Dealing with state corruption was the only issue that likely Democratic primary voters saw Nixon doing a better job on than Cuomo in the September 10 Siena poll, 42-39 percent.
Insurgent candidates can benefit from an incumbents lack of urgency. A Quinnipiac University poll similarly found Cuomo with a 36-point lead.
"He is going hard, but I think what that shows is that he is actually scared because he understands that we've got a real hunger for progressive change in NY state and he doesn't have a record to run on", Ms. Nixon said Wednesday on the "Breakfast Club" radio show.
A mailer from the state Democratic Party that suggested that Nixon is anti-Semitic also backfired for Cuomo.
And in July, Mr. Cuomo was dragged into ugly headlines after the architect of his six-year-old plan to revitalize upstate NY - dubbed "Buffalo Billion" - was convicted in a bid-rigging scheme involving state contracts worth hundreds of millions of dollars.More news: Meghan Markle's Sister Samantha Unleashes on Duchess With Profanity-Laced Nickname

Cuomo "now seems poised to overwhelm Nixon", Greenberg said.
T.I. is so high on Cynthia Nixon's political platform - at least the marijuana parts of it - and vows she's got his vote for governor, even though he doesn't know who she is. and can't possibly vote for her. She said Cuomo has not aggressively fought for the funding in Albany. His running mate, Lt. Gov. Kathy Hochul, is facing a serious primary challenge from progressive New York City Councilman Jumaane Williams.
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.
Two Democrats who were not in the IDC, Simcha Felder and Martin Dilan, also are facing challengers.
In addition to the email, the Cuomo aide attempted to pitch the reporter through text messages, including a text that said, "Hey I got something for you on nixon...."
