As the Senate appears set for a vote Tuesday afternoon on President Barack Obama's jobs plan, one "centrist" senator has already decided to cast a "No" vote.

Sen. Joe Lieberman (I-CT) appeared on Fox and Friends and told co-host Gretchen Carlson why he doesn't support the bill, centering on how he wants to focus more on "the debt."

"To me, the number one thing we should be doing is to deal with the debt," he said. "The President's jobs bill costs almost a half of trillion dollars. I much rather save it for a real genuine debt reduction program. To me, the most important thing you can do is to restore confidence to the people who manage corporations and invest in our economy. I don't think this bill does enough to be worth spending half a trillion dollars."

Noticing the tone of his statements, Carlson said, "Senator, you're sounding like a Republican."

Lieberman laughed and replied, "No, I'm an independent."

"But I think any Republican in the Senate would say exactly what you just said," Carlson said.

"Well, as an independent, I have the freedom to say what I think," Lieberman said.

With no Republican senators showing any signs of voting "Yes," the bill looks certain to fail in the Senate, which was expected to take a vote on the measure later today.
