If Dan Rather had grossly and deliberately misrepresented something that Ronald Reagan had said, here's what would have happened:
It would be all over AM radio.
Howard Kurtz would write several columns in the Post and discuss it frequently on CNN.
The New York Post would headline "Rather Kicks Reagan's Corpse!!"
The New York Times would run a prominent feature about it,
Editorial boards from around the country would weigh in on this travesty.
Every columnist - conservative and liberal - would be falling all over themselves to condemn Dan Rather.
It would for years to follow become the reference point for "bad journalism."
Now we have Brit Hume clearly deliberately distorting something FDR said, and several other Foxmonkeys following suit. Will any of the above happen? No. Brit Hume has no standards. Fox News has no standards. And, none of the usual suspects even tries to hold them to any standard.
So, when people ask why the "left" can't collect any scalps, that's why. You can't shame people who have no shame.
