Gov. David Paterson just threw a potential wrench into the convention plans for both the Democrats and the Republicans, pledging to call special sessions that would force them to remain in Albany if they don’t get a budget done before then.

After declining to call five-way public leaders meetings for more than two months, Paterson has now called one for two weeks in a row, informing lawmaker at today’s (fruitless) get-together that there will be a repeat performance next Tuesday, May 25.

That’s the first scheduled day of the Democrats’ convention in Rye, at which the entire statewide ticket, including presumptive gubernatorial nominee, AG Andrew Cuomo, is to be selected.

Tuesday is already a session day. Ditto for Wednesday (Day 2 of the convention). Paterson said he plans to be in Albany for five days next week and will call special sessions for Thursday and Friday to make sure lawmakers are there, too.

Paterson threatened to do the same the following week, when the Republicans are scheduled to hold their convention in Manhattan.

“It is my opinion that it would be irresponsible for any of us to be thinking of politics while the budget is still out there,” the governor said. “And I’ll be here every day next week and I will call special sessions on Thursday and Friday to make sure all of you are here next week and the week after.”

“So you conventioneers, Democrats and Republicans, might want to think about spending the time in Albany as opposed to any place out because that’s our obligation to the people of the state of New York.”

Paterson urged lawmakers to buckle down and make hard decisions about spending cuts – even if they fear it will hurt them in the upcoming election season at a time when anti-incumbent sentiment is already very high.

“Yes, some of the decisions that will be made could theoretically hurt you in this upcoming election,” Paterson said.

“…Recognize the fact: You’re going to have to go against your political instincts and do what’s right. And I think the people of the State of New York will hear you. Because the people of the State of New York are ahead of us. They have already started making those reductions in their own lives.”

“…Don’t think that this anger out here that the public is fomenting is at the decisions that have been made, it’s at the absence of decisions and inaction.”

UPDATE: CapConf’s Jimmy Vielkind reports the governor walked this back somewhat during the post-leaders meeting Q&A.
