There are at least a couple of changes I'd like to see made with our system. For starters I don't think our politicians should be able to choose our judges nor should they be elected. They should be independent of partisan politics and decide based on the Constitution and their own conscience.
I also don't like the idea of political parties. Anyone should be able to run for office without having to follow some sort of party line. Again, they should be able to vote based on the needs of their constituents and, again, of their own conscience.
And term limits are fine, if they stick to it. The Republicans pushed an amendment to limit the President to two four year terms because they didn't want another FDR. Just forty years later, they wanted to repeal that amendment. Why? Because they wanted another four years of Ronald Reagan. American hypocrisy in action.
