So President Barack Obama goes to Capitol Hill over the weekend and late Tuesday Senate Democrats reach a healthcare compromise on a public insurance option (Republicans oppose the legislation so every Democrat vote is needed to move it along). OBAMA/

Lots of day-after grumbling from both sides of the political spectrum: The Chamber of Commerce still opposes it and liberal activist group said senators had “bargained away the heart of healthcare reform.”

Well, for critics it’s not likely to get any better on the public option front.

If the bill makes it to the final stages before becoming law,  the Senate version would need to be melded with the House version. And a true compromise would require the Senate to take on a stronger public option and the House to weaken its hand.

One lesson from covering Capitol Hill is that nothing is a done deal until the final vote is in.
