Whichever GOP candidate is elected, you can be sure it will be a constitutional conservative and that will be the kiss of death for Obamacare.
Going to the USSC now is the only hope for Obamacare. In the end, it may not make much difference since the GOP will defund it or legislate out of existence if the GOP takes control of the Senate.
From your keyboard to God's ears...
I would be more optimistic if the Republicans acted as if they noticed some of the most damaging parts of Obamacare are not in the Healthcare Act at all but in the Finance laws and other Obamenacts.
