So what do you call a president that doesn't govern by political polls but what he promised he would do when he campaigned?

If you are a progressive its "a dictator"

If you are a conservative its "a guy with intestinal fortitude"

votes/taxpayers/citizens have for so long been governed by politicians with an ear to the dog whistles of lobbyist, and an eye on the polls they can't recognize and don't know how to react to a true independent and individualist thinker because their heads implode
