text: Also states that tend to vote one way or another often do not get visited because there is no point in trying to convince a state to vote for you that is definitley already going to vote you, to vote for you, and vice versa.  Swing states with high populations are really the only states that are visited.  It is no promise that the potential president will go to every state or even every region, but they will more likely than not visit different states than they would have before.  If popular vote decided who would become president, it likely would no longer be true for presidents to only visit swing states.
