I liked Hillary Clinton, but she truly is a ruthless person

She has no shot of winning the nomination, yet she is doing her best to prevent Obama from prevailing in November. I can't see a logical reason for her to stay in the race. She's delaying the party from unitying and preparing to take on John McCain. I still feel Obama has the upperhand against McCain, but he could use all the time he can get. The Clintons should be ashamed of themselves. How can she claim to be for the people when her selfishness is hurting the people.
