Television evangelist Christian right makes up like 0.0001% of the American population. They are only slightly more numerous than unicorns in the U.S. so who cares what they have to say. Most Christians don't.
You obviously know very little about the USA whose AM radio is filled from one end of the dial to the other with right wing "Christian" radio stations which blurt out all sorts of propaganda. While they are certainly have their right of free expression, anyone with the slightest knowledge of the USA is fully aware of the amount of influence these people exert. CBN, the LaHaye's, Christian Coalition, Focus On the Family, and others continue to exert much influence over right wing voters.
