This is the reason, IMHO, that Liberal talk radio never gets off the ground. As long as the government subsidized NPR exists and the not-even-remotely-about-profit AirAmerica operates, Liberal talk radio will never have the opportunity to develop appealing and profitable programming.
The failure of Liberal talk radio is just another example of Liberal good intentions and government largesse supressing innovation and risk taking and preventing the very thing they mean to promote.
John Stossel rocks!
