I don't think Romney wants to destroy this country, but I do think he Romney is absolutely correct when he says the biggest difference between him and Obama is competence.
My fear, is that many of Obamas disastrous policies, if implemented by Romney, could become far more dangerous. Romneys motivations may not be malevolent, but his ability to carry out plans of Obamas policies, are still more dangerous.
Interesting point. Also, having a Republican do it would essentially neutralize the ability of the GOP to halt or hinder the transformation of the US into a socialist paradise. And I don't think Romney would be really averse to the police state aspects of doing so, either.
In any case, I was out and missed the debate (I'll try to watch a replay later) but it sounds as if things went about as expected.
