Part of the problem with the US is that it is just so damned big and so diverse. I' not sure democracy scales well.

To take your example of Denmark; Denmark has less population, and half again as much area as Massachusetts. Comparisons between the US as a whole, and individual European countries don't always make the most sense; the more appropriate comparison would be to the EU, to have the same kind of multitudes of disparate people under a common banner.
