Gov. Andrew Cuomo is not running for president. But he is involved in who is seeking the Democratic nomination.

Cuomo’s preferred candidate is former Vice President Joe Biden, who’s candidacy the governor has been taking up in public since Jan. 2. Biden formally entered the nominating contest on Thursday and, as CNBC reported, Cuomo is providing access to his considerable fundraising network.

But why play Ned Stark to Biden’s Robert Baratheon?

Here are some possible reasons why:

Generational Appreciation

President Trump’s election in 2016 not only re-organized the Republican Party, it began a reformation of the Democrats as well. Very broadly, what once was a party with defined Clintonite and populist-progressive wings is shifting. The wings are now divided between consensus-driven Democrats and progressives. Cuomo is firmly in the consensus camp, making Biden a more comfortable selection for him.

But it may also be more complicated than that. Cuomo likely sees few peers in the battle for the Democratic nomination who have been in politics as long as he has and who have the experience that he has other than someone like Biden. Cuomo in recent weeks has shown he is confounded by the current political climate that he thinks has a poor reward system. Instead of producing accomplishments, it’s producing retweets.

Biden was born 10 years after Cuomo’s late father, former Gov. Mario Cuomo, and is 15 years older than the governor. But in a rapidly changing and diversifying party, Biden, like for many voters, represents a version of comfort food for Cuomo.

They’ve Worked Together

Cuomo tagged onto to Biden early on. He’s spoken of working with Biden’s late son, Beau, while both sat in attorneys general offices in New York and Delaware.

While vice president, Biden traveled to Albany to talk — at length — with Cuomo about infrastructure. They held similar events subsequently, with the same guffaws about Biden’s assessment that LaGuardia Airport is like a “third world country.” Cuomo takes this to be Bidenistic wisdom about the need to upgrade the airport. Biden’s provided political support for Cuomo as well.

He appeared at the state Democratic Convention in 2018, along with Hillary Clinton and DNC Chairman Tom Perez, to lend establishment support to a governor facing a primary challenge to his left flank by Cynthia Nixon, an actress and public education advocate. Biden later appeared in a TV ad for Cuomo’s re-election as well.

Cuomo has had ties to the other 2020 contenders. He, of course, worked with U.S. Sen. Kirsten Gillibrand at HUD. U.S. Sen. Bernie Sanders helped defuse tensions within the New York delegation — which included a number of his supporters — at the 2016 national convention by appearing at a breakfast event.

Sanders later provided a helpful progressive endorsement for Cuomo on his college tuition plan that expands state assistance and the boosting of the minimum wage in the state. Progressives in New York have pointed out that the details of both fall short (college tuition, broadly is not “free” in New York, but provides last-mile assistance up to a certain income level, while the minimum wage will hit $15 in the New York City area, but at an undefined time upstate).

Cuomo Thinks Biden Can Win

He’s said it himself. And it would not be surprising if Cuomo has polling that susses this out as well, along with questions about what trait Democratic voters care about most in a nominee: electability.

But Why Biden?

The Democratic Party is changing. There are more women and people of color seeking the Democratic nomination than ever before. South Bend Mayor Pete Buttigieg would be the first openly gay man to serve as president. Biden would be the oldest man ever elected and the first white man nominated by the party since John Kerry in 2004.

But Cuomo may have reason to trust his political instincts. This time last year, Nixon’s campaign was getting underway. On paper, Cuomo had the advantages of labor support, western New York, and a vice grip on suburban voters. Then Alexandra Ocasio-Cortez won her primary against incumbent Rep. Joe Crowley and conventional political wisdom seemed like it could take a loss as well. But ultimately Cuomo, with his campaign war chest providing scale in a big, expensive state to run in and a coalition of voters prevailed later in September.

For Cuomo the lesson learned in the third term campaign as an affirmation: What he’s doing politically, works.

A Biden-Cuomo ticket is almost absurd on its face, aside from the lack for gender, age and racial balance. It’s almost impossible think of Cuomo playing second string as vice president, a job that is only as powerful and potent as a sitting president wants. Some who have worked with him think he may be interested in a cabinet post like Homeland Security secretary, a job that allows him to command a massive bureaucracy, something he’s shown he enjoys overseeing and reshaping in New York’s state government.

Cuomo, however, has insisted he loves his current job. And he’s fundraising this spring to keep it.
