Outspoken documentary film-maker Michael Moore Monday endorsed Democratic White House hopeful Barack Obama, decrying the "downright disgusting" campaign tactics of Hillary Clinton.
Moore, whose latest movie Captain Mike Across America tracks John Kerry's doomed 2004 bid for the presidency, said he had not given a "rat's ass" who won the nomination this year as long as a Democrat triumphs in November.
But having excoriated Clinton for her 2002 vote in support of the Iraq war, the Oscar-winning writer and director now accused the New York senator of "stoking the fears of white America" against the mixed-race Obama.
Writing on his website on the eve of the Pennsylvania primary, Moore said that in recent weeks, "the actions and words of Hillary Clinton have gone from being merely disappointing to downright disgusting."
