In the past, elections notoriously were called early on the networks before the west coast voting booths were closed, making many people feel like their votes didn't matter.
(Obama's victory wasn't called until 11 4 years ago when the west coast polls closed.)
Then again, I bet that problem returns if we have another landslide election.
I have always voted during the day (when I went to the polls) so it didn't really affect me. However, I can see where it does take something out of it when you know the winner before your vote is cast. IF your guy didn't win why vote & if you're guy did win, why vote?

Of course that's excluding the importance of whatever propositions are on ballots.
