You don't get to have a New York Times bestseller without liberals reading it too. That's just the thing. When Al Franken writes a book, no cares. Conservatives, however, love reading Ann. And many liberals feel inexpicably compelled to read it. Its like waiting for a pregnancy test. Most of them just can't wait.
That's because many liberals don't need anyone to tell them what to think.
Liberals generally aren't into the "echo chambers" and "parroting" that makes up much of the political discourse in this country.
Think about it.... if the right is so correct why do they have to continually reinforce this all the time and make sure they are continually telling people how to think.
Seriously, you should really think about this... and study similar episodes in history. (hint, read some of the stuff written by hitler's propaganda minister for a start)
