Early voting is probably a forerunner of how voting is likely to be conducted in the future.
Oregon, for instance, is already conducting many of their elections entirely by mail. Interestingly, while early voting appeared to 'slightly favor' Republicans, they did not enjoy a big advantage. Because there are more Republicans than Democrats in Arizona, Republicans constituted a larger percentage of the vote than Democrats. There was no difference between how men and women felt about the issue. This is the type of issue that really divides a community because it is felt so strongly by those who support and oppose it.
