But with political activity heating up in Congress over the sequestration cuts, Lieberman’s comments inject a dose of skepticism to calls from both parties about going over the "fiscal cliff" at the end of the year.
Sen. Patty Murray (D-Wash.) this week gave a speech saying Democrats should not reverse sequestration or extend the Bush-era tax rates at the end of the year unless Republicans agree to raise taxes on the highest-income earners.
Republicans have responded by accusing Democrats of wanting to allow job losses to occur in order to increase taxes.
The sequestration cuts last week became part of the presidential race, with presumptive GOP nominee Mitt Romney accusing Obama of harming the military by allowing the cuts to occur.
While Lieberman said that the odds were against sequestration occurring, he emphasized the fact that the cuts still are possible, and are currently mandated by law. He argued that the brinkmanship from both sides over end-of-the-year negotiations could make them more likely.
Most believe that a solution to the sequestration cuts, whether via a delay or alternate deficit reduction, will not occur until after the election in a jam-packed lame-duck session.
Sen. Kelly Ayotte (R-N.H.), who appeared at the TechAmerica event with Lieberman, looked ahead to that debate by urging Democrats not to use the military cuts for leverage.
“I don’t think that our military should be used as some kind of a political chip for other issues,” she said.
