Don't have to 'change' the regime, WB. States can just choose to ignore (un-Constitutional) mandates on the basis of the Tenth Amendment. Just have to be ready to assume self sufficiency; which is what will be the ultimate outcome of economic collapse and 'regime change' anyway.
The Truth of Numbers and Natural Law runs the show...sooner or later. If you're looking for Justice (not mercy)...that's where it is. Mercy is found in the realm of the Spirit, and in the hands of Jesus. Though I'm sure the Commies think that their ideology is the secular verision of *real* mercy...minus the justice part.
To your OP...yeah...if upon collapse, Obama moves to take the stuff that a lot of the Red places have saved up, for what they believe is an imminent collapse...then there will be *Spring*.
