In most presidential elections, the two candidates spar over issues. The president campaigns for his party's nominee in hopes of continuing his legacy.
Democrats champion liberalism, Republicans conservatism. In numerous press conferences, journalists try to force newsworthy and embarrassing admissions from the two candidates.
