All along the Obama-maniacs have used racism as their trump card.  Any criticism of him was racist, pure as simple. 

So according to this piece at the NY Daily News, that is also why Hillary won’t quit:  Racism and bigotry.  So be happy all you non Obama-maniacs, according to this, the secret is out and the only reason you do not like him is because you are a racist bigot.

 Ugly truth why Hillary Clinton won’t quit (emphasis mine)

While the case for Hillary Clinton to stay in the race is shakier than ever, one ugly reason for staying in could be found Tuesday amid the ruddy, sun-kissed Hoosiers who cheered her on to victory at the Indianapolis Speedway.

…a young white girl…

there were almost no African-Americans to be seen. Many in the white, working-class crowd were simply not ready to back Barack Obama - for reasons that are disturbing.

“I’m kind of still up in the air between McCain and Hillary,” said Jason Jenkins, 32, who cited information from a hoax e-mail as a reason to spurn Obama.

“I’ll be honest with you. Barack scares the hell out of me,”he said. “He swore on the Koran.”

So they single out one crank who believed that idiotic email.  So if whites don’t trust him for his alleged Muslim faith and his skin color, how does he attract any at all?

Obama did manage to pull in many white voters, but still encountered similar sentiments from a man who refused to shake his hand at a diner in Greenwood, Ind.

“I can’t stand him,” the man said. “He’s a Muslim. He’s not even pro-American as far as I’m concerned.”

Such feelings leave Clinton and the Democratic Party in a tough spot. With the largest number of remaining delegates now being party insiders, they have to decide if Obama can overcome enough of that antipathy - essentially deciding if enough working-class whites will back away from the black candidate, whether because of the false Muslim rumors, the Rev. Jeremiah Wright flap or old-fashioned racism.
