In Oregon, all elections are conducted completely through mail. It's awesome; I had weeks to fill out the ballot and they mailed us 2 thick books that had statements from all sides AND full text + summaries of all ballot measures. Even though it took me like 3 hours to vote, I feel more confident than I ever have with my choices.
Every state should have this system...seriously.
I mailed the ballot over a week ago. Straight Democratic Party line was the way it shaped up this time around...except I voted for the campaign finance reform measures that all the parties oppose.
