Just in time to prove a major migraine for the Clinton campaign for the May 6 Hoosier State primary, a YouTube video alleges Clinton backer Mickey Kantor once derided Indianans as "sh*t" and "white n****rs." Fellow NewsBuster Seton Motley and I reviewed the video. There's no doubt Kantor actually said "It doesn't matter if we win. Those people are sh*t," but there is a dispute over who "those people" are and if the second slur is doctored. [see video embed below fold]

Ben Smith at Politico.com reports that D.A. Pennebaker, director of "The War Room" from which the clip is taken, insists the "white n****rs" comments were doctored. Au contraire, says the editor of the video, who insists he merely "enhanced" the audio to bring out the barely whispered epithet.

What's more, Smith reports, Pennebaker says Kantor was referring to then-President George H.W. Bush's political advisors as "sh*t", not the people of Indiana themselves:

He said the initial expletive referred to the anticipated reaction in the Bush White House to the fact that Ross Perot's polling numbers were holding strong.

"What he says is he's surprised Perot's numbers are holding," said Pennebaker in a brief phone interview. "He says they must be shi**ing in the White House."

The second expletive, he said, appeared to have been entirely fabricated, with new audio dubbed onto the original movie.
