Actually most of the EU democracy processes are easy to understand. I'd like to see a European comment on the efficacy of their process. Most follow a proportional system, some follow a mix of proportional and single member single district (winner take all), and Great Britain is winner take all.

They also have much more party discipline. Somebody voting for a party knows the type of policies that party will enforce, and if people are not crazy for the policies being passed, the vote in a different party in the next election.

Also, I would argue that lobbying is more prevalent in the US. Low party discipline + the much greater "need" for money = more money influence.
