I used to watch the Morning Joe show, I still do sometimes, and for the same reason it's pure politics (their downside they don't cover morning traffic for the DFW area).
I found their evening line up, to be annoying. Olbermann is nutso, I don't care for Rachel, and haven't watched Ed Schultz. Ehh, I can read the news and not have to listen to any of them, plus Family Guy is on at night.
