I don't want to spill too much ink on this, but I do want to make essentially one point: postmortems on the right today are circling the idea that the demographics of the country have changed, and the GOP has failed to respond adequately to that. Both of these things are true, but I think they point to a more fundamental truth.There's more at the link, of course. And you should read it. You may not agree with some of Brian's observations, but you'd be well advised to consider them carefully.
Obama won this election because he was running to be president of the country that actually exists. Romney lost because he was running to be president of a country that does not.
The larger question is this -- could the country that doesn't exist ever exist again? Because if it can't ever exist again, we have much to think about.
