I think further proof of the media bias is:
The tea party caucus is depicted as nazi, paid, rent a mob people and is reported as radical and the minority.

http://cpc.grijalva.house.gov/If Dubya Bush were still President and the progressive caucus is attacked, via the IRS; with even an inkling of a tie to the Bush White House (much less if Dubya had a union there) President Bush would be impeached, removed from office and crucified.
