First of all, I think you meant runs, period, not home runs. Secondly, the argument that you need to capture many states to reflect broad support has been shown to be bogus in a variety of ways on this list. The electoral college is arbitrary and inconsistent, it does not accurately advance the interests of any particular minority, and so on. No need to rehash here. I doubt you or many others really disagree.
But most importantly, I think the analogy is a poor one, because we expect and desire this inconsistency in baseball, and sports in general. Not only is the World Series inconsistent due to the multi-game format (why not just play one 60 inning game over a few days?) but scoring is made erratic by the inning breakdown in games (why not just give a team 27 outs in a row to each team?) These erratic effects are by design. We say "may the best team win" because, on some level, we are aware that they may not. This uncertainty is part of the excitement of sports: sports are filled with surprising heroes and storybook last-second wins. This is the stuff of dreams and it sells tickets. These are NOT properties I want in an election method. I do not want any fringe, "Cinderella" candidate to be able to capture the presidency on "any given November." I do not want to see "hope spring eternal" for the American Nazi party. I want boring, predictable elections where the best candidate wins. -Adam
