Obamacare dies under it’s own weight without the mandate.
Also, the fact that the authors took specific action to omit the severability provision, in order to gain the votes to pass, means the court can NOT overlook that intent in their ruling......TODAY!
You are using logic and business sense and reaching a conclusion. The problem is, the congress nor the Court shows that kind of common sense in way too many cases. Obama Care SHOULD die under it's own weight without the mandate. Unless of course the tax payers hold it up. The severability clause SHOULD make a mandate only ruling impossible. But remember, this is essentially the same court that upheld CFR. Fear the mandate only ruling.
A strike down of the mandate with no mention of the severability is the most likely outcome. In very short order, there would exist no private insurance companies - a crisis that demands governmental action regardless of party in power.
