Why, then, is the president limited to serving two terms? There's essentially squat keeping the president doing anything at all resembling what he said he would do during his second term. (Said by a non-American, who views this aspect of American constitutional law as distinctly anti-democratic.) I'm also completely ignoring the degree to which voters are paying attention, how much the debate is swayed by powerful people to meaningless issues while the politicians run amok of everything etc. etc.
