ICYMI, here’s the lead item today’s Morning Memo:

The New York City-based war over charter schools will reach a head in Albany tomorrow, as hundreds from either side descend on the state Capitol for dueling rallies.

On one side: Former NYC Councilwoman and charter school operator Eva Moskowitz, who is furious with NYC Mayor Bill de Blasio for reversing co-location decisions by his predecessor, former Mayor Bloomberg, that would have allowed for the expansion of three schools operated by her Success Academy network.

Moskowitz has cancelled school tomorrow at all 22 of her charters, and plans to bus angry parents, students and teachers to Albany to protest de Blasio’s decision.

On the other side: De Blasio and his allies, who had already planned to be in Albany Tuesday to rally for his ever-more-out-of-reach plan to let the city tax wealthy residents to expand pre-K and after school programs in the five boroughs. De Blasio last week fanned the flames still further by calling Moskowitz’s rally a “sideshow,” insisting he would not be deterred by her plans.

There is a belief among de Blasio backers that that Moskowitz has launched her competing rally with the tacit approval – if not outright encouragement – of the pro-charter Cuomo administration, which is at odds with the mayor over pre-K funding.

Just last week, Cuomo was praising the charter school movement and its departed “champion” (Bloomberg), while refusing to weigh in directly on the co-location argument.

A Cuomo spokesman did not return an email seeking comment Sunday night.

Meanwhile, Senate GOP Leader Dean Skelos told the NY Post he’s prepared to fight on behalf of charter schools during the ongoing budget negotiations with Cuomo, Assembly Speaker Sheldon Silver and IDC Leader Jeff Klein.

Skelos called de Blasio’s co-location decision “unconscionable.” He also expressed concern about the administration’s effort to redirect a $210 million construction fund used to build space for charter schools toward pre-K, and its plans to charge better-financed charter schools rent.

Not everyone in the charter community is at war with de Blasio. Twenty-three charter organizations have signed onto a Feb. 27 statement calling Moskowitz’s competing rally “not the right approach at this time,” and refusing to participate.

“Tuesday is not a day to be divided,” the letter reads. “Those rallying in Albany next week should stand together with the city and advocate – side by side – for our children, particularly the most underserved, and all of whom are public school students.”
