Why won't Hillary bow out?

The media hasn't been able to contain their elation at the presumptive nomination of Barack Obama. They don't even try to hide it or show any objectivity.

Naturally, Hillary Clinton is not bowing out of the race. Is she waiting for the tape of Michelle Obama's anti-whitey rant to emerge? It's rumored she said the way to solve the problem of black on black crime is to divert it to black on white. That will go over well with the voters. You know if that video is out there someone will find it. The media will try to hide it, but you can't keep that cat in a bag for long.

If the rumors are true and this video surfaces it could totally derail Obama's campaign. How many Americans want an America-hating racist as the First Lady?
