Here’s one thing Gov. Cuomo and Mayor de Blasio have in common: A lot of official favors get done for their fat-cat donors — and both keep insisting it’s all just a big coincidence.

The latest Cuomo case concerns Crystal Run Healthcare, already under federal investigation over $400,000 in possibly illegal donations to the gov’s campaign and whether they’re linked to a pay-to-play scheme.

Now, despite earlier denials from everyone involved, it turns out company execs got a private sitdown with top state officials in 2015, just 12 days after Albany started seeking applications for $1.2 billion in development grants. Crystal Run wound up with $25.4 million of that (the only for-profit company to qualify) for two projects.

Team Cuomo insists those projects never even got mentioned at the meeting, saying it was only about Medicaid. Yet the Albany Times Union reports that an e-mail sent two weeks later by Crystal Run’s chief legal officer stressed that company execs had “shared our vision for growth,” including the two “expansions,” with the health commissioner and a top aide who worked in Cuomo’s office.

Both officials, the e-mail noted, “were, obviously, supportive, as we are bringing real jobs to real people” — and had agreed that “further discussion was warranted” with the state economic-development agency “at the highest levels.”

The e-mail, which was sent to development officials, explicitly asked for state funding. Two months later, Crystal Run’s CEO gave Cuomo’s campaign yet another donation, this time $50,000.

No matter how bad this might look, Team Cuomo insists it was all completely on the up and up. That’s Cuomoland: Everything is just one happy coincidence after another.
