Maura Keaney in The Guardian:
Joe Lieberman has become the Balloon Boy dad of the Senate Democratic caucus, a fame-whore so addicted to media attention that he hatches ever-more-desperate and risky schemes that sell out his “family” to earn press attention.
Progressives can only hope that, like Richard Heene, Lieberman will finally be exposed as a fame-seeking fraudster after his latest stunt, Tuesday's threat to filibuster any bill for healthcare reform that includes a public option.
No one who's been paying attention should be surprised by Lieberman's move, yet the Washington press corps responded as if they'd never heard of the boy who cried wolf. This is Lieberman's schtick, the only act that's ever consistently gotten him ratings.
