How come Rachael Maddow can go on her own little witch hunts and no one on the Right cries out foul?

Because Maddow bases her story on facts not twisted opinions she pulled out of thin air. Glenn Beck has said publicly he doesn't feel fact-checking to be necessary. And she actually lets the other side give their point of view when they are invited to her show rather than losing her temper and calling them unpatriotic communists (*cough* O'Reilly *cough*).
