That could be the work of diligent Rand cultists, swarming the polls. Rand's books sometimes get up there in the top 10, next to Brothers Karamazov and such. It can't be due to merit. Hubbard cultists behave the same way.
Atlas Shrugged is her anti-state/pro-individual liberty masterwork and that is why they are trashing this movie.
I thiink it's counterproductive for conservatives to rally around someone like Rand. I wouldn't want to see conservatives rallying around Hubbard either because he was, like Rand, a cult leader and a nut.
In our modern times it is the best ally Christianity and Conservatives will ever find. The non-religion and anti-opression tenets staunchly oppose Evil Islam. The individual liberty and laissez-faire capitalism principles stalwartly oppose liberalism, socialism and communism and fascism.
In spite of Objectivism rejecting faith, its embracing rational self-interest and personal happiness as the guiding purpose of life grants any sovereign individual tacit license to hold personal beliefs as desired. Qbjectivism could never be an enemy but is an unwavering Paladin standing at the shoulder of our Civilization.
