CNN's Jake Tapper gave a full segment to Democratic Congressman Bennie Thompson calling Supreme Court Justice Clarence Thomas an "Uncle Tom," but the broadcast networks completely ignored the controversy on Wednesday evening.

The networks' blackout of a Democrat using a racial insult against a Justice shows a clear double standard after their deluge of coverage of Los Angeles Clippers owner Donald Sterling's racist remarks about his players. And just last week, the networks highlighted Republicans and conservatives who supported rancher Cliven Bundy's stand against the federal authorities but who had to backtrack after Bundy's racist rant went public.

As CNN reported, Thompson also called Senate Minority Leader Mitch McConnell and other opponents of ObamaCare "racists." Yet none of the broadcast networks thought this newsworthy on Wednesday evening.

Instead of reporting Thompson's remarks, ABC devoted a 23-second news brief to which Disney princess was voted most popular. The NBC Nightly News spent over two minutes reporting on the cognition and intellect of dogs.
