2 or 3 SC Justices and however many other appointments, there will be NO going back.
NO Mitt Romney SC Justice will be any better than an Obama appointee. Obama and Romney agree on all the issues that Sotomayor, Ginsburg, Kagan, and Breyer do: ObamaRomneycare socialism, abortion on demand, registration and eventual confiscation of guns, jackbooted federal power triumphant over the states, enviros win every time, fostering dependence of the citizen on the federal government in every possible way.
Romney's past choices in Taxachusetts show the way he will choose as President.
