First, a joint House-Senate version has to be hammered out. It's entirely possible that the product of that joint committee will be a bill that does not garner the needed votes in either the house or the senate.
Second, as someone mentioned, these current bills are garbage. They mandate healthcare insurance, but essentially leave a person to pay whatever an insurance company sees fit to charge. Philosophically I don't believe in government price regulations, but I also don't believe one should be forced to engage in a business transaction.
Third, whatever does pass is likely to face a constitutional challenge. It's one thing to say that if you want to drive a vehicle you have to have insurance because driving a car is not seen as a basic right (you can always walk). Saying that you must pay money to a private business simply because you exist is a whole different ball game.
Finally, I think the ideal situation here would have been for Congress to use their inter-state commerce power to break down regulatory barriers in the States that stifle competition. Of course heaven forbid the Congress actually uses the commerce clause in a manner it was originally intended for lol. In the alternative, a full balls to the wall socialization would still have been preferable to this mess of a bill.
