Is this option available in every state? I was able to vote for the delegates that favored my candidate. If this is an option to voters in other states, voters have an opportunity to send a message to their superdelegates. I honestly don't remember having this option before but I've never voted in such a closely contested democratic primary.
For the record, I voted for Obama today but I see great strengths and weaknesses in both candidates and I will support and vote for whoever wins the Democratic nomination in the general election.
