Just a comment partially relevant to the electoral college: No, I'm not going to tell you whether you should keep it or not that's completely up to you. It certainly looks old fashioned to Europeans, but there is one advantage I have not seen mentioned yet:

There is often a trade-off between total justice to each vote(r) and stability of a government. A couple of voting systems give precedence to stability of government by giving the winning party more than their due share of the seats (electorate,...). In Britain, usually the relatively largest party gets the absolute majority of the seats, in other countries (as Germany) there is a cutoff at a certain percentage of votes so that only parties with more than e.g. 5% of the votes get seats in the parliament. The USA system also has some of these built in mechanisms (one of them the electorate college) to ensure that the stronger party gets more than its due share and is able to make a strong government.

There is an obvious disadvantage to all these systems: It can happen that the will of the majority of the voters is different from the majority in the parliament. In Germany, for instance, in the 1969 election, Willy Brandt came to power (with my voice!) and made a much needed major change in our politics angainst the will of the majority of the people. A right wing party had 4.6% of the votes and with a tiny bit more votes for them, Brandt would not have been elected. But since all of their votes were discarded he had a comfortable majority in the parliament.

Now look around the world to countries with voting systems that are extremely fair to the will of each single voter, like Italy (until five years ago) and Israel. They have but a succession of governments dependent upon single votes (in the parliament) and their governments are blackmailable by tiny parties with one or two seats (and very individual interests).

My impression is that the completely fair voting systems have on the average the disadvantage of leading to unstable governments (we choose our present system among other reasons from our bad experiences with the completely fair before Hitler voting system).

The fledgling democracies in the East of Europe in the last two decades looked to the Western democracies for models for their voting systems. Most if not all of them choose systems which were not completely fair but ensured that the majority had a bit of additional advantage. They opted for stability at the expense of fairness.

The electorate college is surely not the only way to ensure a strong president and is not infallible. But don't you agree with me that those democracies have more stable governments that have slightly unfair voting systems? I'm sure, however, that there are exceptions that I do not know of and I'd love to know them.
