I understand the Congress and Senate systems. I also understand the old one that a week is a long time in politics. In the UK the Parties produce their manifestos prior to the election and then the losers spend the next five years bitching about how they lied just to get elected and haven't delivered a single policy. Tony Blair had his Third Way, Margaret Thatcher had a clear agenda, does the US have genuine domestic and foreign political goals? I suspect that the US has become almost democratically ungovernable. Maybe it never has been.
