The Senate Republicans used the so-called “cash-for-casinos corruption scandal” – otherwise known as the AEG debacle – to great effect during the 2010 election cycle, which, as we know, ended with their triumphant return to the majority.

In case you need a refresher:

A bombshell IG report released in October 2010 found Senate Democratic Conference Leader John Sampson, former Senate President Malcolm Smith and Sen. Eric Adams might have violated the Public Officers Law in “unduly conferring benefits or favoritism and acting in violation of their public trust” when awarding the politically connected AEG the Aqueduct racino cotnract.

The IG said the bidding process had been “rife with inside dealing, secret lobbying and more than $100,000 in campaign donations from the bidders.”

The AEG deal had already fallen apart, but the damage was done.

The IG referred his findings to the now-defunct Legislative Ethics Commission, the US Attorney for the Southern District of New York, the Manhattan DA’s office and the state Commission on Public Integrity (also defunct) for “review and any action they deem appropriate.”

So far, no charges have been brought against anyone. But the Republicans aren’t ready to let the issue die.

Today, the state GOP released a statement slamming Democratic Sen. Joe Addabbo for hosting a $2,500-a-head fundraiser last night at the Aqueduct raceway, which is located in his Queens district. The Republicans noted Addabbo was mentioned 38 times in the IG’s report, and he received nearly $300,000 in campaign contributions from those implicated in the scandal.

“What is it about people always returning to the scene of the crime,” said GOP spokeswoman Becky Miller.

“One would think the last place Joe Addobbo would want to be seen would be at the casino at Aqueduct Raceway. But time and again we see the arrogance of career Albany politicians on display, and evidently that is what we are seeing here again.”

Addabbo is facing a challenge from Republican NYC Councilman Eric Ulrich, who might himself face a primary challenge from former Giuliani administration attorney Juan Reyes.
