The Senate Democrats are poised to announce a new slate of leaders to head up the DSCC as the party licks its wounds in the minority and plots its 2012 grudge match (barring any special elections) against the GOP.

The line-up reflects the new power structure within the Democratic conference, which was also on display in Minority Leader John Sampson’s selection for ranking committee memberships and conference leadership posts.

All the key constituencies are represented: Upstate, women, Latinos, blacks, the suburbs and the power boroughs (Brooklyn and Queens).

As has been previously announced, Queens freshman Sen. Mike Gianaris will be chairing the DSCC, replacing Sen. Jeff Klein, who stepped down from his No. 2 deputy leader position and led a four-senator revolt from the Democratic conference.

The new co-chairs are Sens. Neil Breslin, who replaced Klein as Sampson’s deputy; Andrea Stewart-Cousins and Jose Peralta, who bumped Sen. Kevin Parker from the position of whip for the Democrats.

“With our new leadership team in place we will mobilze Democrats, strengthen our political operation and recruit good reform-minded candidates to win back the majority,” Gianaris said.

“I thank Senators Breslin, Stewart-Cousins, and Peralta for their committment and efforts in the days and months ahead. Their expertise and assistance will prove invaluable as we take the necessary steps to bring the Democrats back to the majority.”

In a series of interviews that followed his ascent to the DSCC chairmanship, Gianaris predicted the Democrats would be back in the majority prior to the 2012 elections.

But it appears at the moment that the GOP is safely entrenched in the majority, with some additional extra breathing room (at least when votes are concerned) provided by the foursome internally being referred to as the “Kleiniacs.”

Gianaris also pledged a full review of the DSCC, which is some $3 million in debt, thanks in no small part to its heavy reliance on big-ticket political consultants during the 2010 cycle. The former assemblyman, who is known for his fundraising prowess, said he would be bringing the committee down to the bare bones and then rebuilding.

The previous co-chair line up had been: Sens. Liz Krueger, Malcolm Smith and Antoine Thompson.

Smith, of course, lost most of his power in the wake of the 2009 Senate coup. He is no longer Senate president, and has been relegated to the position of conference secretary. Thompson lost his WNY seat to Republican Sen. Mark Grisanti in one of the most Democrat-dominated districts in the state.
