Maureen Dowd column on Atlas Shrugged the movie.
As Maureen mentions, the Republicans, especially Republican primary voters have to be reminded that Ayn Rand slept around, was a hardcore Atheist and was one of the primary advocates of wholesale abortion of her time. So it is not her taking the moral high ground with her book The Virtue of Selfishness or as that times spokesperson for Social Darwinism alone that makes her so popular these days. It is a simple ideology of rewarding the wealthy and letting the poor drop dead.
A reminder. It is the CATO Institute that is behind this resurrection of Ayn Rand and feeding us silly Libertarian clowns like Ron and Rand Paul. The CATO Institute was founded with money from the Koch Brothers who still fund it with $16 million a year.
