The message in Barack Obama's latest email plea to supporters is this: You can never be too careful.
Obama's campaign has argued forcefully that whichever candidate ends up with the most pledged delegates -- those won from state primaries and caucuses -- should win the Democratic nomination. His aides, claiming a pledged delegate advantage of 135, say that superdelegates -- the party czars who hold the keys to this year's prize -- should follow the will of the people.
But just in case, they're asking supporters to write personal letters.
"We firmly believe that the candidate who has won the most pledged delegates -- the result of having more voters in more places supporting your campaign -- will be the Democratic nominee," Obama's campaign manager, David Plouffe, wrote in an email to supporters today. "But to be safe, we are working to attract the support of 'superdelegates' -- party officials and Democratic officeholders from across the country -- who also have a vote at the Democratic National Convention."
So they're asking people to write to superdelegates and share anecdotes about why they support Obama.
"The story of where you're from, what brought you into the political process, the issues that matter to you, and why you became part of this movement has the potential to inspire someone who could cast a deciding vote in this contest," Plouffe wrote. "Our staff will compile stories from supporters like you and make them a key part of the conversation with superdelegates as Barack asks for their support."
