Washington (CNN) - Sen. Joe Lieberman told CNN Tuesday he is "moving in the direction of" voting for the Democratic health care bill, if the provisions allowing for early Medicare buy-in and a new public health insurance option are removed. And the Connecticut independent senator dismissed liberal criticism that he is acting out of bitterness over his loss in the Democratic Senate primary in 2006.
"Well that's just poppycock," he told CNN senior congressional correspondent Dana Bash. "….If I had any sense of vendetta against the Democratic Party I wouldn't be in the Democratic caucus today. I'm an independent Democrat."
His position was based on policy, not politics, he said.
Lieberman also said that even though the prospect was unlikely, he could not rule out running as a Republican in 2012: "All options are open," he told CNN.
Lieberman also denied that he was making demands because he enjoys the spotlight, pointing to a campaign launched earlier this week by progressive activists to convince the nation's largest breast cancer non-profit organization to dump his wife Hadassah Lieberman as an honorary spokeswoman. "I can tell you that inside myself I have not enjoyed this period of time. I've done what I thought was right, but it's no fun to have your colleagues be angry at you. It's no fun to have your wife attacked. But, you know, you got to do what you think is right.
"So, no. I'd be happy to have some time out of (the) limelight."
Lieberman said he had not yet decided whether to vote for health care reform. "Here's what I'd say. I've always wanted to be able to say yes to health care reform. But there were some parts of this bill, public option, Medicare buy-in that I thought would essentially lead to a government takeover of health care in America, which I'm against, because I think it would reduce quality and increase prices and certainly raise the debt, and taxes."
Lieberman said that if the public option and Medicare buy-in are taken out – and following a review of the actual language and a cost estimate of the Congressional Budget Office – he would then "be in a position to do what I've wanted to do, which is to say yes to health care reform.
"I'm moving very much in the direction of saying yes, pending just seeing what I've been told is happening with the bill."
After Lieberman joined Senate Democrats at a meeting Tuesday with President Barack Obama, the president said Congress was "on the precipice" of passing a sweeping health care reform bill.
"There are some differences that still have to be worked on… (but) there is broad consensus around (a set of) reforms," he said.
Unanimous Republican opposition to health care legislation so far means Senate Democrats need the backing of all 60 members of their caucus – including Lieberman - to end debate on the bill and move to a final vote, which will be decided by a simple majority.
