These PR shows are hardly informative. You get influenced by style instead of substance. Furthermore it makes more sense to judge people who run for a public office by their past actions instead of their empty election promises (which are usually released en masse during these TV debates). Romney won't e.g. talk about his job-destructive work at Bain and Obama won't talk about the massive drone war in Pakistan that kills civilians and low-level Al-Qaeda activists.
Judge 'em by their actions, you want man to do a job and not a rhetorician or a guy who is skilled at covering his turds with glitter.
