@Brandon9000,
Or voted FOR McCain. This election was marked by an unusual amount of goodwill towards both candidates -- less voting against than usual, more voting for.
Which is what makes the approval ratings pertinent -- there are a lot of people like Phoenix who didn't vote for Obama but who are now part of the "we" that have come together to support him.
And it's still noteworthy that
enough people voted for Obama that he's actually less than two hours away from becoming president. That's something that would have been unthinkable in the not-too-distant past.
