If I were forced to choose between the following 3 entities/groups as to who the factual evidence suggests was trying to "put the screws to the voting public":

1. Presidency

2. Repubs in Congress

3. Dems in Congress

I'd have to pick #2. Overwhelming disposition of evidence pointing in that direction.

In the spirit of your point: now imagine what those folks would be willing to do to your healthcare. Actually, we don't have to imagine. Look at their actions.
