Jason, I would be very interested to know whether you think a Parliamentary form of democracy, with a safety valve second chamber, is possible in countries the size and as diverse as the US?
Yes. The US is far more homogeneous than it was when it was founded. States rights have waned steadily in the face of a growing federal behemoth, and most people do not consider themselves to be citizens of their state primarily and Americans secondarily. It may sound bizarre, but prior to FDR, under whom the federal government became the pre-eminent authority, most people more concerned with the day-to-day politics of their state and city. They thought of the governor more than the president, and truly were regional in outlook becuase it was regional politics that affected their lives the most. Now things are very different. We're far more mobile, far more connected by media, and our economies have moved from local or regional to national to global. Few states maintain a distinct identity as reflected in their government. Any identity we think of today comes down to regional cultural variations, only minorly political affiliations. There are exceptions (New Hampshire, Hawaii, and Texas come to mind), but on the whole, it is far easier to transition from one place to another and that's reflected in our focus on national politics.
My version of the perfect US government is a hybrid of what we have today. I'd love to see the lower house be elected in the same manner as the German Bundestag except for state representatives. The Bundestag gives each person two votes, one for a candidate, another for a party. This gives the kind of proportional representation I believe is so lacking in US politics and would give greater voice to the many people who feel they have to settle for bad or worse. The lower house would retain sole powers of taxation and legislative creation. From that house, the PM would be elected by the parliament.
The upper house would be much like our original Senate; appointed by the governors of each state, two to a state, and would retain the authority to approve Supreme Court appointees and ratify treaties. Otherwise, the Senate would remain a deliberative body with the ability to veto House legislation unless the House were able to pass the legislation by a 2/3 vote, in which case the Senate's veto would be overriden. The Senate may return amended legislation to the lower house for consideration up to three times or until a 2/3 vote by the lower house is made. The Senate can also create committees for draft legislation proposals that would then pass to the standing committees of the lower house for consideration.
In the general election the people would vote for their House reps and also vote for a President to act as Head of State, Supreme Commander-in-Chief, and be vested with the powers of dissolving the government, calling elections, and appointing a PM if no quorum could be attained in the lower house. The President would also head the Government Accounting Office, a separate audit department which we have now, to keep track of what government is really spending and how. The President would also act as President of the Senate in much the same way the Vice President does now. The term of a President should be long, perhaps 8 years.
The Supreme Court would carry on much as it has before save that the PM would appoint nominees to the court.
Impeachment and removal process for the President, Senators, and Supreme Court members would proceed, again, must like before. The lower house passes the articles, the upper house would try them. Only the lower house can remove a PM by a vote of no-confidence.
I think that this system would work. It's a bit more complex but it would allow multiple parties and give the people actually more say than they do now. The Senate would be subservient to the states once again, curtailing the power of the federal government. The person of the President relieves the PM of Head of State duties but also acts as an overseer of government by acting as the President of the Senate and having an oversight department under its aegis. The President also acts as a stopgap against government overthrow or abuse of privilege by the PM by being Supreme Commander-in-Chief.
What matters most to most people, is that the Bill of Rights be protected, there is an independent judiciary, and that there is full equality before the law. Beyond that, I believe most would welcome a chance for more enfranchisement.
The biggest hurdles are the present party system which makes any change close to impossible, and the difficulty and gravity of changing the Constitution. In other words, don't hold your breath.
And my advice to Europe is, ditch the entire United States of Europe thing. Unify your damned currencies, create one huge free trade zone, and then let it go. Europe is not the United States. There is no one unifying ideology or a history of immigration and assimilation. You are dealing with a myriad of homogeneous cultures, not a bunch of mutts thrown together. And get the non-European immigrants out before they're butchered.
