The real reason Romney lost
Romney lost because conservative voters failed to turn out.
Conservative voters failed to turn out for many reasons--poor technology being one of them--but also because they are tired of being betrayed by Republican candidates, and they sensed Romney was a betrayal-in-waiting.
Case in point: Chris Christie, newest beneficiary of Obamacare.
Christie's acceptance of expanded Medicaid funding puts him on the opposite side of the table from the GOP in Congress, which needs to reform entitlements to make federal ends meet. Obama has vowed he will not cut Medicaid (he has already cut Medicare Advantage, however). Christie is now firmly in Obama's corner.
I don't see how Republicans are going to recover from things like this. The party may truly be over.
