Former Mayor Ed Koch is so far having better luck getting the AG contenders to sign his reform pledges than Democratic gubernatorial nominee Andrew Cuomo is with his “New New York Agenda” plea.

To date, three of the six candidates vying to replace Cuomo have formally put their names to Koch’s trio of New York Uprising PAC pledges, one plans to sign but hasn’t done so yet, and two are still reviewing it.

Sen. Eric Schneiderman was the first to sign Koch’s pledges, which call for nonpartisan independent redistricting, ethics and budget reform. But he had a head start because legislative candidates and incumbents got their pledges before the non-Albany AG candidates got theirs.

Sean Coffey has also signed. (I believe he was No. 2). Coffey has made a point of calling for more stringent ethics reform than his primary opponents, saying the bill sponsored by Schneiderman, passed by both houses of the Legislature and vetoed by Gov. David Paterson doesn’t go far enough in its disclosure requirements.

Staten Island DA Dan Donovan, the lone GOP AG contender, signed his Koch pledges today.

Eric Dinallo and Nassau County DA Kathleen Rice just received their NY Uprising pledges, according to their respective spokespeople.

Rice will not only sign, but will be releasing her reform agenda in the coming days, according to her spokesman Eric Phillips.

Dinallo is still in the process of reviewing the Koch pledge, which he also just received, said his campaign spokeswoman Lauren Passalacqua.

Assemblyman Richard Brodsky is also in still in “reviewing” mode, according to his campaign manager Jon Lipshutz, who also noted that the Westchester lawmaker’s own reform agenda includes a nonpartisan redistricting commission.

As for Cuomo’s pledge, Wayne Barrett notes today that only two of the would-be AGs – Rice and Coffey – have so far signed.

As for the others, Dinallo has flat-out refused to sign, saying in a statement that “AG’s office must remain separate from the governor’s,” while also stressing that he agrees with much of Cuomo’s “New New York Agenda.”

Brodsky and Schneiderman are still reviewing the Cuomo pledge. Lipshutz noted to me that Cuomo has “not yet solicited for us to sign,” while Koch sent out an e-mail yesterday urging the assemblyman to do so.

Schneiderman has stressed the importance of “independence” between and AG and the governor to whom he (or she) serves as top legal counsel and also must sometimes investigate.

This has been meant to cast Cuomo’s supposed preference for Rice in a negative light, but also puts the senator in a position of being unable to get too close to Cuomo without stepping on his own argument.

It’s fairly safe to bet at this point that neither Cuomo Schneiderman nor Brodsky will receive a pre-primary endorsement from the anti-Albany Cuomo – should he choose to give one. The AG recently seemed to be trying to distance himself from Rice, saying during a radio interview that he’s “looking at” Coffey and Dinallo, too.

He didn’t even mention either Brodsky or Schneiderman.
