The modern conservative movement has 3 important blind spots, Achilles heels if you will
1. The idea that America is in some sort of post racial environment. Racism is alive and well in America, it can clearly be seen in some of the attitudes towards and treatment of President Obama and in many other areas on American life. Conservatives seem to not want to acknowledge this, which is why commentators such as Juan Williams (http://www.youtube.com/watch?v=PWaOcJlaQvU ) becomes such an important voice, moderating intelligently between conservatism and a pragmatism acknowledging what life in American is actually like for African Americans.
2. While conservatives glorify and love the idea of the free markets they need to see that free markets simply do not exist in the realm of multinational corporations. The collusion between the financial services industry, large corporations and our government has completely corrupted any functionality of the free markets. Until crony capitalism is ended, or at least abated in some way, you cannot keep assuming that the mechanism of the free market is going to solve anything.
3. The environment – Ronald Regan said government should only do what it has to do; protecting the environment is one of these jobs. Due to the deadly complicity of big business and big government the “free market” cannot address the protection of the environment, therefore government (sadly) is the only player left standing.
