I have a suspicion that a complex voting system (like, anything more complex than "most votes win") would spread greater confusion and distrust, that's just my pessimism. I would be happy if we could have a national popular vote to choose the president, that reduces complexity. I'm wary of anything more, though I do like that there are now some experiments here and there with other systems. Edit: I've recently come to the conclusion that the real value of elections is as a national show of force. "1xx,000,000 of us are here and paying attention and expecting the government to respond to our interests and willing to do something about it"
