Who is Andrew Cuomo?

Cuomo has been governor of New York State since 2011. He was elected in 2010 and re-elected in 2014.

Prior to becoming governor, he was New York State attorney general from 2007 to 2011.

Before being elected in 2010, he ran for governor once before, in 2002, but lost in a primary to Carl McCall.

His father Mario was a three-term governor in New York State. Andrew worked on several of his father's successful campaigns.

The younger Cuomo also worked in the federal Housing and Urban Development department during Bill Clinton's presidency. He was the head of the department during Clinton's second term.

What platform is Cuomo running on?

Cuomo has tried to position himself as a fighter against President Donald Trump. He has said said the Republican president wants to return to an era of greater sexism, racism and intolerance toward immigrants.

The issues listed on Cuomo's campaign website - including civil rights and criminal justice reform, fighting for women's equality, protecting New York's environment and creating a stronger middle class - refer to defending and protecting New Yorkers against extreme conservatives and Washington.

Cuomo has called on state Senate Republicans to codify current federal abortion laws at the state level, in case those laws are changed at the federal level. He threatened litigation if the federal government ends the DACA (Deferred Action for Childhood Arrivials) program for undocumented immigrants who entered the U.S. as children. He has also denounced the Republican-passed federal tax overhaul.

The governor has also been drawn into a war of words with the president in recent days. Trump fired off a series of tweets after Cuomo said America "was never that great" at an event in Lower Manhattan. Cuomo later backtracked from his remarks, but he did tweet a response to Trump that read, in part: "Let's get something straight: America is great because it rejects your hate-filled agenda of bigotry & sexism"

What do his opponents say?

Cuomo is facing a primary opponent, Cynthia Nixon, who has criticized him for not being progressive enough. She has called him a "wannabe Republican."

Nixon supporters say her entry into the race has caused the governor to enact more left-leaning policies, something they dubbed the "Cynthia effect." Examples of the "Cynthia effect" include:

• The governor's proposal for a statewide ban on carryout plastic bags - after Cuomo signed a bill to block New York City's ban.
• Authorizing a study on the legalization of marijuana in New York after previously calling it a "gateway drug." (The state health commissioner says the study recommended legalization of marijuana.)
• Granting New York parolees the right to vote.
• The reunification of the Independent Democratic Conference - a group of Democrats in the state Senate that caucused with Republicans - with Democrats. (Nixon specifically took credit for this.)

She has continuously criticized Cuomo over the state of the subways. She has also been critical of his education policies and his stance on sexual harassment.

Nixon has also been critical of the governor's record on corruption. This has also been a point of contention for the Republican candidate in the race, Marc Molinaro, who has said the governor has enabled a culture of corruption. Earlier this year, Joe Percoco, a former top aide to Cuomo, was convicted in a bribery and corruption trial, and several defendants were convicted in a corruption trial connected to the governor's Buffalo Billion project.
