That's a key point as to why liberal talk radio doesn't work. One of the basic tenets of liberalism is that any position could end up being wrong, if the evidence changes or better arguments are offered. So every liberal position is held tentatively.
Conservatism is simplistic and benefits from the courage of conviction, which makes for more compelling, inspiring talk radio.
I was thinking about this the other day and you summed it up nicely.
A stationís format needs to have an identity. People tune in for various reasons but, like most things, they choose consistency. TKK had a bad start with boringly liberal Eagan and Braude then flipped to a very consistent and entertaining Conservative Michael Graham. Then completely screwed up the drive time going back and forth with a series of hosts, never really finding their way.
Meanwhile, the AM Conservative entry in Boston continues to be strong with no apologies. Jeff Kuhner is no shrinking violet, Rush, Carr and Levin, love them or hate them, you know what youíre going to get.
