I agree with you, but I would refer to my original comment. Walker needs to have a standard, well-thought-out answer for why he left college without a degree. He could allude to trying a couple of fields of study before settling on one; he could say jokingly, that he never could master multivariate calculus and had to re-take it. He just needs to have a consistent story, and one to which many people can relate. Then, he needs to transition from his college "experience" to his public service experience. One that has results, one that he can point to as a success.
Who cares? Also, anyone nosy enough to demand Walker’s transcripts had better be intellectually honest enough to demand Obama’s.
