In the wake of the latest bombshell corruption scandal, which netted two New York City GOP officials from Queens and the Bronx, other party leaders were quick to volunteer that knew absolutely nothing about the scheme to essentially buy a GOP ballot line in the NYC mayor’s race for Democratic Sen. Malcolm Smith.

The scandal netted Bronx GOP Chairman Jay Savino and now former (as of today) Queens GOP Vice Chair Vince Tabone. The Queens, Brooklyn and former Staten Island GOP chairs all told the Daily News they not only weren’t aware of the ballot-rigging scheme, but also were not contacted by federal investigators about it.

That left Manhattan GOP Chairman Dan Isaacs, who is normally a pretty talkative guy. But yesterday, didn’t have very much to say about this mess – or his possible role in exposing it - other than: “It is inappropriate to comment on an ongoing investigation, which I hope is completed as expeditiously and thoroughly as possible.”

Today, Isaacs has expanded on those comments a bit in an email to to Manhattan Republicans, in which he calls the alleged actions of those arrested “an outrage and a complete betrayal of the public trust,” adding: “With three Democrats and three Republicans arrested, it also shows that corruption is not limited to an exclusive partisan provenance.”

“(I)f anyone harbors concern that there is ‘another shoe to drop’ here in Manhattan, I want to take this opportunity to reassure you that there is not,” Isaacs continued.

“Anyone who knows me and has worked with me during my involvement with the Republican Party knows that I value personal integrity over all else. I demand it as much from myself as from those with whom I deal. There is an expectation and covenant that I have with those who have given me the responsibility to lead our local Republican organization which I simply will not betray.”

Isaacs is supporting supermarket mogul John Catsimatidis in the GOP NYC mayoral primary. (Catsimatidis, for the record, employed Tabone on his campaign and in his business, but has since suspended him from both positions. Catsimatidis also revealed he has been working with the feds on this investigation).

Isaacs also used his email to promote his committee’s annual “spring fling” fund-raiser, which is taking place at the Women’s National Republican Club in Manhattan tonight. He called the event “a good opportunity to begin to restore trust in the concept of an honest and participatory political process.”

The Manhattan GOP has been having trouble raising money, and certainly needs the influx of cash this event might bring.
