He'd probably try his best to sort out corruption in the way he sees fit, but end up being used by someone for most of his presidency. Then near the end of his term he'd figure out what was going on, and kick that guy's ass, managing to fulfill all of his campaign promises at the last second, although not in the ways that he originally wanted. He'd willingly step down after one term because his love of propane is too great.
