Spoiler Still?

Joe Lieberman's firm opposition to a Public Option has been widely publicized, and everyone's wondering if he's buying in to the new Senate compromise. Signs from Joe indicate he's not giving up yet on being a spoiler.
“I am encouraged by the progress toward a consensus on proposals to send to the Congressional Budget Office to review.  I believe that it is important to pass legislation that expands access to the millions who do not have coverage, improves quality and lowers costs while not impeding our economic recovery or increasing the debt. “My opposition to a government-run insurance option, including any option with a trigger, has been clear for months and remains my position today.
The new Senate compromise would allow the private sector to offer the alternative national health insurance option instead of it being offered by the government, but it would contain a trigger clause if those policies failed to materialize as desired. It would also expand eligibility for Medicare down to those age 55.
“Regarding the ‘Medicare buy-in’ proposal that is being discussed, we must remain vigilant about protecting and extending the solvency of the program, which is now in a perilous financial condition.
Sounds like Joe is still planning to oppose this legislation.
“It is my understanding that at this point there is no legislative language so I look forward to analyzing the details of the plan and reviewing analysis from the Congressional Budget Office and the Office of the Actuary in the Centers for Medicare and Medicaid.”
Also expressing some concern over the legislation is Russ Feingold.
Feingold told reporters he was concerned that stripping healthcare reform legislation of the government-run public health insurance option could result in a giveaway of federal dollars to private insurers.
Why do Democrats hate the private sector so?
