MSNBC cracks me up.
They're dedicating an entire segment every hour to expressing outrage over Letterman's remarks about Sarah Palin, but they don't seem to have any problem with far worse remarks which they pay Pat Buchanan to repeat on their network.
Adding... Speaking of Mr. Buchanan:
The Southern Poverty Law Center reports that MSNBC’s Pat Buchanan has invited the editor of a white nationalist, anti-immigrant website to speak at the upcoming conference for his group, the American Cause.
