Nothing has really moved it at all. Not half a billion dollars in combined expenditures by all sides; not Romney's vice-presidential pick of Paul Ryan; not any speech by either President Obama or Romney. Not even Vice President Joe Biden opening his mouth. Why?
Abandoning his former supporters, his former colleagues, and his president, makes him in some ways the personification of the Romney-Ryan-Ayn Rand glorification of self-interest. He's got his, America. Who cares what you got?
