Thomas Defrank of the New York Daily News nails the reason that Hillary is still in the race; the discomfort - whether racially motivated or otherwise - with Obama by white, working class males:
With Hillary Clinton still winning this vital core constituency of the Democratic party by nearly 2-1 in most races, party leaders and Superdelegates are hesitant to tell Clinton to drop out, fearing a mass exodus of white men to John McCain in the fall.
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."
It's not much of an argument. But it's all she's got at this point which is why she may very well stay in the race all the way to the convention. Perhaps Obama will slip up. Perhaps his wife will cause his candidacy more trouble. Perhaps there is something else in his past that will emerge between now and the convention.
On such slim hopes rests Hillary's chances.
