absolutely spot on.
i'll tell you something else. i think that they were right that there was enthusiasm amongst republicans for replacing obama. this enthusiasm was real. but the price of enthusiasm from the right was loss of appeal to the middle. and so romney got fewer total votes than mccain.
instead of enthusiasm implying high population, the enthusiasm was coming from a smaller population of highly motivated people. it meant the folks voting for romney were especially enthusiastic. they turned up to events. but an enthusiastic voter still only has a single vote.
electoral support is bimodal by nature. but obama's support sat closer to the middle spot where the population bell curve is at its greatest.
it appears that white men are much more likely to be far right. they are enthusiastic about far right ideas. but there just aren't enough of them to win an election.
that's the way i interpret things, anyway.
