Getting Obama out of the White House is almost certainly a matter of national survival. Vote accordingly.
The main thing that keeps me - barely - on the Romney side is the SCOTUS.
The main argument against a Romney victory lies in the cycle enunciated by one Alexander Tytler:
From bondage to spiritual faith;
From spiritual faith to great courage;
From courage to liberty;
From liberty to abundance;
From abundance to complacency;
From complacency to apathy;
From apathy to dependence;
From dependence back into bondage.
The more quickly we can pass through the apathy/dependence/bondage phase, the sooner real rebuilding can begin.
