He has lied and lied and lied repeatedly. He is no longer to be trusted. Sure he says he'll caucus with the Democrats, but he's made so many promises he's broken.
And as Jane Hamsher points out, he's abused the position of committee chairman:
While it's one thing for Obama to personally forgive Lieberman for the race baiting and other gutter tactics that he engaged in on McCain's behalf during the campaign, it's quite another to let the chairmanship of such an important committee, which Lieberman has used for years to prevent Senatorial investigation into no-bid contracts and contractor abuse within the Department of Homeland Security, to serve as an olive branch.
Lieberman, many will recall, was responsible for holding hearings into the government's response to Hurricane Katrina. But after winning his 2006 election with the help of the GOP, he decided it would be too "divisive" and refused to do so.
Good governance is going to be about more than passing new legislation, it's going to be about cleaning up the mess that has been made over the past 8 years. It's going to be about weeding out the graft and greed and corruption that has caused American taxpayers to foot the bill for outrageous deficits. The military industrial complex has been bilking the Pentagon and the Department of Homeland Security with no-bid contracts for things nobody needs that we're not allowed to know about for years now. The only way we're going to find out about these abuses, and right then, is if our elected officials accept that responsibility.
Not only is Joe Lieberman not doing that job, as Chairman of the Department of Homeland Security Committee he's keeping anyone else from doing it. He happily allowed a seat on the Homeland Security Advisory Council to be doled out as political patronage to a corrupt Bush Pioneer. He has no interest in cleaning up the mess he helped to make.
Is his continued happiness worth the cost of healthcare? Of the environment? Of putting Americans back to work? Of reducing our dependence on oil and getting the economy back on its feet?
Allowing Lieberman to retain control of a committee where he has done nothing but suppress meaningful oversight is going to be an awfully bitter pill to swallow when we're told that the price of "change" we all thought we were voting for is going to be too high.
