Someone needs to explain to Governor Cuomo that the way to win the African-American vote isn’t by alienating Jews.

Speaking at a Baptist church in Harlem yesterday, the governor briefly acted as if he were at a Friars Club roast, pointing out political strategist Hank Sheinkopf in the audience, who was wearing a yarmulke and sitting in the front row.

“Catholics basically believe the same thing as Baptists believe. We just do it without the rhythm. But we try. We try. We are not as without rhythm as our Jewish brothers and sisters,’’ Cuomo said to the audience.

In the Trump era of political baseball, the governor’s mistake would barely get him on first base but it makes you wonder if he’s getting worried seeing Cynthia Nixon taking swings in the on-deck circle.

With her campaign just a week old, it’s Nixon who seems polished and focused with Team Cuomo showing some jitters. A top supporter of the governor, former City Council Speaker Christine Quinn, called Nixon “an unqualified Lesbian” which then forced a quick apology.

Right now, the campaign seems to be Cuomo versus Cuomo – with Cuomo losing.

Someone should point out to Cuomo that two New York Jews – George and Ira Gershwin wrote the definitive toe-tapper -- “I Got Rhythm” -- back in 1930.

Meanwhile, it seems like we have a race for governor on our hands.

Who could ask for anything more?
