The rapid-fire arrests of two of the three most powerful men in Albany are no doubt causing considerable alarm for the capital's ethically impaired denizens. As in any organized-crime investigation, prosecutors are turning low-level players into informants to get to the big fish, and the people they've turned so far are pretty big fish themselves. That was the case in the criminal complaint revealed yesterday following the arrest of Senate majority leader Dean Skelos and his son Adam.

The charges against the two are based on extensive cooperation—in exchange for leniency—by an executive at a gas and water management company, and more notably, by a man presumed to be Charles Dorego, senior vice president at the development company Glenwood Management.

Glenwood Management, as readers may recall from the indictment of former Assembly Speaker Sheldon Silver, is one of the largest political donors in the state, giving prolifically to members of both parties and all arms of state government, including a total of $1.45 million to Gov. Cuomo. Silver's prosecution depended in part on the cooperation of a lobbyist working for Glenwood, but Dorego is more deeply involved with the company. The latest federal complaint indicates U.S. Attorney Preet Bharara's office only convinced Dorego to play ball last month, when most of the wiretaps and email intercepting would have been done already. If the charges against Silver and the Skeloses are any indication, Glenwood is privy to politicians' secrets and feeling the pressure to cough them up.

One upstate state senator told Capital New York that it seems weird how only select beneficiaries of Glenwood's largesse have gone down so far.

"If the political donor's been giving a lot of money to everybody, maybe a question is how come one of the many get indicted and others don't," Sen. John DeFrancisco said. "I can't imagine."

An anonymous lobbyist told the website it's only a matter of time.

"If Dorego is involved, then you can bet more trees are going to fall," the operative said.

Albany is famously run by three men in a room, and two, the Assembly speaker and the Senate leader, have been brought up on charges since the last election cycle. That leaves Gov. Cuomo as a final, climactic trophy for Preet Bharara to mount on the wall, along with a lot of other, lesser targets for the culling.

But with history as a guide, it's a safe bet that merely locking politicians up won't be enough to clean up New York politics. After all, Skelos is the fifth straight Senate leader to face federal charges. And when Sheldon Silver left the speakership, Bronx Assemblyman Carl Heastie took the reins, and as has been documented since, he has ethical problems of his own.

Also in Skelos news, Senate Republicans spent three and a half hours last night discussing whether or not to oust Skelos as leader. Ultimately, they decided to stick by the embattled pol, but they aren't eager to discuss why. Many declined to comment, though one offered this tepid note of support: "The presumption of innocence remains. That's how the conference feels about it," said upstate Senator Jim Seward.
