You don’t “restore the Republic” by “replacing” a socialist welfare scheme with your own unconstitutional programs. The Constitution of the United States does not grant the national government jurisdiction over the people’s health.
What "unconstitutional" programs did Palin propose to replace Obamacare? She would repeal Obamacare and return it back to the free market, with the obvious exception of Medicare/Medicaid and even that would be gradually phased out.
