@maporsche,
You're totally correct on 1 and 2, and I don't think that the Dems really are trying to hide their vote using deem-and-pass. Hell, they
already voted on the bill!
3 doesn't matter, the Dems learned in court that they couldn't stop such maneuvers a few years ago. ANY arguments against this process have pretty much been slapped down by the court.
The arguments the Republicans are currently employing are, as you say, equally shallow.
4, I don't know if I agree with your projections. The CBO projects considerable savings over the 20-year period. Addition of a public option or a medicare expansion would increase these savings, which is something the Dems are going to continue to try to do. Even if the CBO is way off, the bill is still likely to be deficit neutral.
