Why is radio so conservative? Why are there so many right wing talk programs on the air?

Ken: For the past 10 years conservative views seem to have been quite popular. Radio is in the business of providing people with what they want to hear. The popularity of conservative views seems to have started right around the time when the GOP took both houses of congress back in mid 90's, after the Democrats had held congress for several generations. During the 70's and the early 80's, liberal talk shows were the norm, and conservatives were seldom heard. These things appear to go in cycles.
