Hillary supporters wont vote Obama, if he wins the nomination. Hillary supporters only please?

Why wont you support the democratic Nominee. if he wins in a legit way ?He has more legislative experience then Hillary has, if you count the state senate. He's just as smart or even smarter then Hillary is when it comes to intellectual ability. His policies are similar to Hillary.I listen to people that are so pissed off blacks in m are supporting him, well the reason is because Bill Clinton single handedly pissed off every black person in the country, by comparing Barack to Jackson. Can you please name specifically why as a Hilalry supporter you wouldn't vote for Barack..don't say experience neither has decent experience
