> Lieberman, 67, used his deciding vote in Congress to help strip out a provision for government-run medical insurance, intended to set up competition to the abuses of private companies, by threatening to filibuster the legislation.
> Senate leaders agreed to drop the public option for all in favour of allowing people over 55 to buy into an existing government-run scheme for the elderly. In September, Lieberman supported the measure, as he had when he was Al Gore's running mate. But just as it seemed that a deal was done, Lieberman scuppered it by announcing that he had changed his mind and would block any bill that expanded government insurance coverage. Obama gave way.
