Interesting: Ugly truth why Hillary Clinton won't quit

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.

With Clinton posing alongside pioneering Indy speedster Sarah Fisher, 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."

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."
