Gubernatorial hopeful Rob Astorino and his fellow members of the GOP statewide slate will be announcing the results of their very successful petition drive to create the independent “Stop Common Core” ballot line for the November general election.

At 9 a.m., the Republicans plan to file more than 62,000 signatures at the state Board of Elections in Albany.

Astorino, his running mate, Chemung County Sheriff Chris Moss; Onondaga County Comptroller Bob Antonacci, the GOP state comptroller candidate; and state attorney general candidate John Cahill will then be making public appearances across the state to discuss the filing.

(Moss and Antonacci will be in Syracuse, while Astorino and Cahill will be on Long Island; details of these events appear below).

The Stop Common Core ballot operation was organized by veteran GOP political operative Vince Casale and Astorino’s campaign manager, Michael Lawler.

The Republicans believe this is the largest petition operation in New York history, surpassing the Working Families Party’s 1998 filing, which organizers said included some 60,000 signatures.

In 1994, then-state Sen. George Pataki’s campaign filed about 54,000 signatures to create the “Tax Cut Now” party.

The Stop Common Core operation will qualify in all 27 congressional districts, organizers said. State Election Law requires a minimum of 100 signatures from a majority of districts.

According to Casale, this effort brought together volunteers from across the state – Democrats, Republicans and independents; teachers, students and parents – all united in their opposition to the controversial new standards.

The issue certainly resonates with voters. Yesterday’s Siena poll found 49 percent of New York voters – including 53 percent of independents and 60 percent of Republicans – believe the Common Core standards should be stopped, which is something Astorino has pledged to do if he’s elected.

Cuomo has sought to distance himself somewhat from the Common Core, taking action this past legislative session to temporarily shield students’ test scores and teacher performance evaluations from being impacted by the state Education Department’s flawed rollout of the standards.

But the governor continues to support Common Core as a concept.

Today is the first day to file independent petitions; Tuesday, Aug. 19 is the deadline. Several thousand more Stop Common Core signatures are expected to be filed by that deadline by Senate and Assembly candidates who also want the additional line.

The GOP isn’t alone in its effort to create an independent line for its candidates to run on in November.

Gov. Andrew Cuomo and his fellow Democrats are doing with the same thing with the “Women’s Equality Party” – an effort to harness the power of the abortion-rights debate, which served President Obama so well in his 2012 re-election campaign.

It just so happens that Cuomo’s running mate, former Rep. Kathy Hochul, is holding the latest in a series of events on the Women’s Equality Party today. She’ll be appearing in Kingston with Democratic state Sen. Cecilia Tkaczyk.
