Senator McCarthy stopped them cold but was then destroyed by them and their liberal media. The commie-liberals still control the old time media, newspapers and non-cable TV.
The key aspect of the liberal media is that it represents failed concepts and must lie about those failures. Liberal media must lie about the folks who it relies on for political power, the democrats. Thus, when the the democrats tell the liberal media to lie about the personal corruption of one of its leaders, the media follows orders. And, this is why any attempt to build a viable liberal talk radio/TV cable position is doomed to failure.
Liberal talk radio hosts will be allowed to mouth only the lies of the dems. If most people wanted lies, they would watch CBSNBCABCCNN or read the Times. The classic is Begala. He is a pure liar; nothing he says is not for a propaganda purpose. So, there is absolutely no valid reason to watch or listen to him.
The beauty of liberal talk radio is that it has to fail. On one hand, the host must first be a dem liar. But, OTOH, if he is not and tells the truth on only a few issues, he will have to become a non-liberal radio host. Honesty is the flush to liberal s**t.
Please see my tagline. I think we both get it.
