"Sen. Max Baucus (D-MT) hosted a meeting of moderate Democrats this afternoon, including Sens. Mark Begich (D-AK), Mark Pryor (D-AR), Blanche Lincoln (D-AR), and Kent Conrad (D-ND), to compare notes on health care legislation. But, as is becoming a common theme around these parts, they say there's not much to discuss until they can see the bill with a CBO score."
You can add Joe Lieberman to that group.
I suppose these Democratic senators, mostly from Republican leaning states, spent some time examining the returns from New Jersey and Virginia. That's why they're now focusing on cost.
