Why are Clinton supporters still holding on??

Seriously, I don't get this. Clinton and Obama both ran a good race. There could only be one nominee. You pout because she didn't get nominated, you pout because Obama didn't pay off all the debt SHE incurred, which he got donations for. You wanted her to be placed in nomination at the convention, and she was. What the heck else do you want? From the outside looking in, it looks silly, childish, and like you're sulking. You would allow a republican to destroy the nation because you're mad she didn't get the nomination. I don't understand...
