Over the weekend, Barack Obama won Guam's Democratic delegates by seven points, but it's been weeks since he posted a big victory. He once called Indiana primary the "tie breaker" with Hillary Clinton. His big lead in North Carolina made it a "fire-wall," like Ohio was for her. If Obama won both, it could be the end of the Clinton campaign, but now it appears both states are closer than anybody expected. Indiana and North Carolina are complicated in different ways. Do they want to hear about "change" or "bread and butter" economics? Does a "gas tax holiday" sound like a good deal or cynical promise?
