We also run the risk of Roberts once again helping Obama get his wish.
Given his track record thus far, the odds of that being the case - and of conservatives being frustrated once again - are considerably greater than the odds of the outcome postulated in the OP.
Frankly I have no hope that we will see a solution to this nation's current predicament coming OUT of Washington DC; SCOTUS included. My one and only final hope for a peaceful solution will be for the states to severally reassert their native authority over the Federal government but the odds are not great for this, either.
