I don't see why this precludes consideration of the impact of the voting system though.
My point was that there are two ways of looking at it. People say that Nader spoiled the election for Gore, but in my opinion, Nader was the far better candidate. Why blame Nader and those who voted for him, when it could just as easily be turned around and blame Gore and his supporters for Nader not being elected?
That would not preclude consideration of the impact of the voting system. But in the end, the system is only as good as the voters.
However, I would agree that some changes to the system could improve things a bit.
One idea that's been floated around in the past is requiring all state party primaries to occur on the same day. No more of this "New Hampshire Primary" deciding the candidates for the whole country. Have it all on the same day, and eliminate the conventions, too. They're pointless anyway.
Or another possibility would be to eliminate political parties altogether. Every candidate would be an independent. If they have a certain number of petition signatures, they can get on the ballot. (The same process is used in recall elections.) No party primaries at all.
Also, one thing that's problematic with our political system is that it's so toxic and media-driven - and media are generally thirsty for scandal and drama. This isn't an atmosphere conducive to the best and the brightest stepping up and running for office.
There's an excellent movie with Robert Redford called
The Candidate. It's from 1972 and a bit dated, but it's still a rather interesting portrayal of a political candidate and what it's like to be on the campaign trail. Many of the issues are still the same as they were back then.
