Pay-to-play is the order of the day at Bill de Blasio’s City Hall. And the mayor’s lobbyist buddies are cashing in — big time.

The Wall Street Journal reports that overall lobbying receipts in New York have jumped 15 percent since de Blasio took office, to an all-time high of $71.9 million.

Indeed, the ease with which lobbyists access the mayor is so notorious that the top 10 firms’ client list has grown by more than 40 percent since de Blasio took office.

Let’s face it: Under the mayor who vowed to drive the special interests from power, lobbyists have not only taken up residence at City Hall, they’re running the place.

That’s especially true for three of de Blasio’s closest lobbyist pals — James Capalino, Harold Ickes and Sid Davidoff — and his PR buddy, Jonathan Rosen.

Ickes hadn’t even been a lobbyist here in the 12 years before de Blasio became mayor, save for one client. Since then, he’s collected almost $1 million in City Hall lobbying fees.

Capalino, New York’s top lobbyist, has boasted to clients of his frequent access to the mayor and City Hall, the Journal reported.

And the access he and others enjoy also appear closely linked to donations to the mayor’s re-election campaign or his slush fund, the Campaign for One New York.

Ickes, for example, won a major music festival contract deal for AEG Live on the same day he forked over $13,000 in bundled gifts to the mayor’s re-election campaign.

They’re not alone — other fat cats with a special-interest agenda also make it a point to kick in to CONY or the campaign.

Looks like there are still “two New Yorks” under Bill de Blasio: a profitable one for those who pay and another for everyone else.
