Ryan Grim over at Huffington Post has an interview with Senator Claire McCaskill (D-Mo.) that offers a glimpse of the terrain that lay ahead in the health care battle:

"There’s serious money made in health care in this country and all of that money is pushing back. This will be a fight and it will be an ugly fight. If anybody had some notion that this would go smoothly, or it was going to happen easily, I don’t think they’ve been paying attention," she said before entering a closed-door weekly Democratic luncheon.

The push back from the financial interests opposed to health care reform is being felt strongly in Congress. But McCaskill warned that "whoever wants to be part of bringing all this down … will have to own" the consequences of their resistance. "Everybody’s free to run whatever ads they want to run. I think there’ll be real consequences if we don’t provide stability to the American people as it relates to health care," she said.

McCaskill is right, of course, that financial interests will do everything they can to oppose a strong public option. All the more reason to make sure progressive Democrats draw a clear line in the sand and pledge to vote against any bill that is not available nationwide on day one, and accountable to Congress and the voters
