Libertarian law professor Richard Epstein offers this post mortem of the the Romney campaign:
One of the great tragedies of the Romney campaign is that it failed to spell out, with sufficient concreteness, the risks this nation faces going forward if it does not rein in the size of government.
Intellectually, his greatest omission in the debates was his failure to challenge the president on the administration's stubborn line that tax reductions and deregulation can do nothing to improve the faltering economic position of this nation, with its feeble growth rate and declining standard of living.
I don't believe that most people in this country would take so dismissive an attitude to these fundamental reforms.
