Democratic AG hopeful Sean Coffey welcomed Staten Island DA Dan Donovan to the race today with a strongly-worded statement that deems the Republican “ill-prepared” to fight public corruption and take on Wall Street.

After a prolonged flirtation with a statewide race, Donovan formally announced his candidacy in Lower Manhattan this morning with Mayor Bloomberg by his side.

Coffey called Donovan “well intentioned,” but said his experience is limited to fighting “street crime” and insisted the state does not need a “Super DA” as its top attorney.

“Rather, our AG has a broader array of responsibilities – including protecting investors and consumers from corporate misconduct, fighting discrimination in the workplace, and defending the State’s interests in civil litigation,” Coffey said.

“Mr. Donovan’s lack of experience in these areas of the law raises serious questions. In particular, given the devastating economic consequences triggered by misconduct on Wall Street, the next AG must be able to identify, investigate and prosecute corruption in our complex financial system.

“What are Mr. Donovan’s qualifications on this critical issue? His seeming lack of prosecutorial experience against powerful financial interests would leave New York without the AG it needs to fight corruption on Wall Street and in corporate suites.”

“…I find it troubling that the Republican Party would look to someone with such limited qualifications as the possible candidate to take on the enormous responsibilities of this critical office. I look forward to a robust debate with Mr. Donovan and any Republican challenger about these and other issues facing the next Attorney General.”

Coffey goes on to tout his own record of “accountability and success against some of the most powerful interests on Wall Street.”

One could also interpret Coffey’s slam against Donovan as a sideswipe at one of his Democratic opponents, Nassau County DA Kathleen Rice, whose experience as a local prosecutor is similar to Donovan’s.

(Not to mention the fact that she used to be a Republican – something another of the Democratic AG hopefuls, Sen. Eric Schneiderman, likes to try to highlight in an inadvertent way by referring to himself as the “liberal progressive” in the race).

Rice, who recently picked up the endorsement of the Brooklyn Democratic Party, is viewed as the frontrunner in the Democratic AG field at the moment – largely because she is perceived as AG Andrew Cuomo’s preferred successor.

As for Donovan, he is currently the lone announced Republican AG contender, but he might soon have company.

Onondaga County Comptroller Bob Antonacci had been mulling a challenge to Democratic state Comptroller Tom DiNapoli, but interviewed for the AG’s slot with the state GOP leaders at the Ft. Orange Club last Friday.
