With the time that is left until the primary, it is not beyond reason that Obama could pull out the primary. At the very least, it is looking like he is turning it into a close race. Also, he is making Clinton use her very limited resources to defend a state that she had in the bag. That is money she CAN'T spend in NC or IN.
