Don't hold your breath. dems don't like viewpoints that challenge their current "beliefs." I say current, because their "beliefs" change in direct proportion to current polling data.
Remember, they are the champions of the "fairness doctrine."
Finally, I'll give you an example of the differences between a Republican and a liberal dem: I welcome msnbc.
I even watch it to see their reaction to certain events. You can get a flavor of dem talking points by watching them. I find the advance notice of these little tag lines to be invaluable. It gives me plenty of time to develop devastating counters.
While the dems are threatened by anyone who doesn't regurgitate dnc talking points, most of us Republicans welcome fair competition and exchange of ideas.
If their ideas are better, more people will tune in.
If not, well, you have msnbc.
I did find it amusing how the times was trying to polish the turd that is msnbc. I liked how they stated that olberman was "close" to O'Reily. In the next breath, they mentioned that he routinely gets 1,500,000 more viewers per show.
