The one-term Senator is only one of 26 senators to do so, and puts her at odds with New York's senior senator, Chuck Schumer, a political mentor who helped shepherd the bill.

"There is nothing in this deal that will address the significant jobs crisis we are facing. This deal, cut behind closed doors with zero transparency, is an unbalanced approach that cuts deeply into discretionary spending while being overwhelmingly stacked in favor of large corporations who exploit loopholes and the wealthiest among us. It is simply not in the best interests of the middle class and the larger economic recovery."

In her statement, Gillibrand also echoes some of what Upper West Side--and liberal stalwart--Congressman Jerry Nadler told us yesterday, in which he enumerated the efforts he made to actually deal with the debt ceiling and the nation's staggering deficit.

“I strongly believe America must reduce its debt and rein in federal spending," she says. "Earlier this week, I supported over $2 trillion in spending cuts without additional revenues, and last December I voted to roll back the Bush tax cuts for the wealthiest Americans that are blowing a hole in the deficit. However, I do not believe this proposal is a fair, well thought out, or balanced deal for our fragile economy or the millions of middle class families struggling to make ends meet. "

The vote by Gillibrand shows how far she has gone to endear herself to New York liberals, after a brief Congressional career as an upstate moderate. In 2010, the first time she faced a statewide electorate, Gillibrand was far more vulnerable to a Democratic primary than to a Republican in the general election.

The rest of Gillibrand's statement is below:

“I have not been in Washington long, but long enough to know it is broken. As I travel across New York, the people I meet are focused entirely on jobs and economic security for their families. Congress should take this charge as its own. I will continue to look for bipartisan ways to reduce the debt in a responsible way and create jobs in this struggling economy. The truth is, today we could have gone further in reducing America’s debt with a sensible compromise that both cut discretionary spending and raised revenues. It is unfortunate Congress missed that opportunity.”
