I would consider switching to a different format of audio. Try podcasts and/or satellite radio. With podcasts, you get to tailor make who you tune into, and there are literally thousands of choices. You can either download them for free on iTunes. Or, if you have a smart phone, get a podcast app and stream them or download them straight to your phone. That's what I've been doing instead of radio for a few years now.
There's also satellite radio. I believe XM and Sirius radio are still teamed up. Again hundreds of options out there for all tastes and opinions. Not only will you get several liberally minded radio channels to chose from, but you will also get music, sports, comedy hours, etc. Tons of variety. Monthly charge is minimal. It's a good option if you are in your car a lot.
Either way, TV and radio options are becoming increasingly rare and are highly censored to appease advertisers. Originality and free thought and true open discussion has moved on to different formats. In AM radio land, people seem to prefer podcasts and/or satellite radio. Not only are you less restricted, you also can reach a much, much larger audience. It's internet and satellites (nationwide audiences, or worldwide in most cases) vs the AM band that only reaches a few hundred square miles tops.
