For once, Andrew Cuomo and Bill de Blasio were on the same channel.

Watching NY1 yesterday, you could drink your morning coffee with Pat Kiernan and Andrew Cuomo and have an evening beer with Errol Louis and Bill de Blasio – but don’t dare try mixing those drinks.

A polite but real fight between the two alpha-dogs got some airtime: what to do with the Sunnyside yards in Queens. De Blasio believes that it would be an ideal location for affordable housing – an idea the governor is hardly embracing.

"If we could make it work, affordable housing would always be great. But I think short-term, we need it for a train yard," Cuomo told Kiernan.

"Long-term, we need to do more study. Sunnyside Yards, specifically, is problematic.”

De Blasio responded: “You can't have 200 acres available and all these pressures of affordability in this city and not do anything."

The Sunnyside confusion is just the latest chapter in miscommunication – or non-communication – between the two leaders. From Ebola to this month’s non-blizzard to the minimum wage, de Blasio and Cuomo seem content to be talking loudly to anyone who will listen -- except each other.

Cuomo last year frowned at de Blasio’s call to raise the city’s minimum wage but is now embracing the idea. Rather than be happy with Cuomo’s newfound religion, de Blasio is pressing the issue by trying to get the minimum wage tied to a cost-of-living index.

With Democrats jockeying for national attention in a post-Obama universe, it’s only natural that the governor and mayor are elbowing each other a little in the ribs. And it could get messier if the Democratic National Convention comes to Brooklyn: Do you want to hear from that transformative liberal who is trying to bridge the income gap in the five boroughs or the can-do pragmatic New Democrat who’s finally making New York work?

The governor couldn’t help but remind viewers that he and de Blasio have a long history – with the mayor once working for him during the Clinton administration.

“I used to be the secretary of Housing and Urban Development. I worked with a very bright, young, engaging fellow named Bill de Blasio at that time and this is just what we did – affordable housing.”

“I think the mayor is on the right track,’’ Cuomo said.

Just not those tracks in Queens.
