I can say 2 things based on this election and these results.
1- For a people who claim so much that they don't believe in government, Americans believe a lot in the government. Cause I don't think there is not at all difference in the candidates, nor that their campaigned "policies" will have any real effect on the actual American system, except for that Obama is more to the left, but just a little. Romney campaign was reduced to "I agree with my opponent, but I think he is just wrong, and I'll do the same things he did, except I'll do different." He had very little to campaign on, except on Obamacare, which is ironic cause you can say Romney created it. Obama just continued most of Republican policies anyway.
2- The campaigns did not matter AT ALL. All that money and time was just wasted, cause all the voting was biased among demographics. The whites voted for Romney, males voted for Romney, Women and minorities voted for Obama.
