Obama's sarcastic. McCain's all about "change." What's going on?

Even the political map is starting to look conventional. Obama's advantage there has largely disappeared. Red states like Georgia, North Carolina, and Missouri, which once seemed in play for Obama, now seem less so. Wisconsin now looks like a tossup again, and the old-fashioned battlegrounds of Ohio and Pennsylvania are dead even. Again.

A race that includes the first biracial presidential candidate and a moose-hunting female Alaskan vice-presidential candidate can never be considered typical. But give them time. Before this campaign is over, Obama and McCain will have talked so much about change, they will seem utterly conventional.
