Even before Joe Biden made his announcement this week, Governor Andrew Cuomo said in a radio interview that he believes Joe Biden is the best candidate to beat Donald Trump.

Cuomo and Biden have a longstanding relationship, and according to at least one report by CNBC, Cuomo is now preparing to tap into his vast donor network to assist Biden's run for the White House.

"I think that Biden and he have similar votes, and Biden and he are very close friends," said political consultant George Arzt. "Biden came out for him early in the governor's race. Biden has always been there for him."

But by embracing Biden this early, Cuomo likely has to forgo any ambition he once had to run for president himself in 2020.

"I just don't think that at this time. He looked at the field and he didn't see a path. And so Biden is his best bet and very comfortable for him," Arzt said.

Cuomo has done numerous appearances with Biden over the years, even featuring him as a keynote speaker at his nominating convention for a third term last summer. Cuomo says Biden has the "experience, the values and the qualifications" to serve as the next president.

"What it says to me is that Biden is the most likable white old grandpa who will apeal to the most people, who want an old white grandpa to be president. And by definition, 'credibility' is never going to include women and people of color," said political consultant Alexis Grenell.

All indications are that Cuomo's plan is to run for a fourth term as governor in 2022. He's been fundraising already toward that goal, and has never indicated that he plans on seeking any other office other than governor of the state of New York.
