2008 probably. McCain and Obama were identical, so the election really had no effect on the course the country is on.
Election of the first Black President = Important.
This sounds a bit more like 1996.
Don't confuse precedent breaking with "Important."
Exactly.
This is like claiming that the Election of 1828 (though important for other reasons) was one of the most important in history because it was the election of the first president of Irish descent. Or that 1836 was a very important election because it was the election of our first president of Dutch descent. Or that 1960 (though important for other reasons) was one of the most important in history because it was the election of our first Roman Catholic president. Oh let's go ahead and throw in 1980 (important for other reasons as well) because Ronnie Reagan happended to be the first divorced president in this nation's history.
Sometimes precedence is meaningless. 2008 didn't prove that America has moved past racism, if anything it proved that America is still chock full of racists, from both the left and the right.
