The New Democrats of Western New York, which bills itself as an organization “dedicated to advancing a 21st Century Progressive Agenda,” has unanimously endorsed AG Andrew Cuomo and his running mate, Rochester Mayor Bob Duffy, as well as Sen. Eric Schneiderman to suceed Cuomo as AG and state Comptroller Tom DiNapoli.

The most interesting point here is the in-roads Schneiderman has been making in the Buffalo area, where he picked up the support last week of Sen. Antoine Thompson, the Hispanic Alliance of Western New York, and the local affiliates of Citizen Action, 1199/SEIU and the United Auto Workers.

In a crowded field of five strong Democratic candidates for Attorney General one stood head and shoulders above the rest: Eric Schneiderman, said New Dems president and Erie County Comptroller Mark Poloncarz.

“The next attorney general should be a person not afraid to use the powers of that office for the betterment of our state and country. Eric Schneiderman has proven throughout his career that he is a strong advocate for progressive values and protecting the common good. The New Democrats of WNY and I are proud to endorse his candidacy.”

While Schneiderman has been focused mostly on building support in NYC, from which the bulk of the primary vote will be generated, observers have been pointing out to me that as much as 30 percent of the vote will come from upstate that day.

Sean Coffey told me recently that he’ll be trying to emulate former Gov. Mario Cuomo’s 1982 strategy of wooing upstaters in the hope of off-setting the downstate support Schneiderman has as a veteran Manhattan Democratic lawmaker.

Buffalo played a key role in Mario Cuomo’s success that year, if I remember correctly.

Also, the Erie County Democratic Party was among the first to formally call on Andrew Cuomo to run for governor ess than 24 hours after Gov. David Paterson announced he would not be running this fall.
