There is no better illustration of the intellectual bankruptcy within the loony left than is use of conspiracy theories to explain the obvious.
We see this regularly with immigration policy in America. The simple explanation as to why the general public wants immigration policy changed is that we have seen the abuse that take place. Watching Americans getting fired and replaced in their own country by lower paid foreign workers is sufficient motivation to stand up and say the system is wrong.
The lunatic left has another explanation for public concern over immigration. Resentment over current policy is fueled by one John Tanton and we are all his puppets. A conspiracy theory replaces common sense.
Right now the Tea Party is driving the lunatic left crazy.
