They've given their votes, their money, and their devotion.
And now that Barack Obama is president-elect, his camp is asking supporters for their opinion.
Campaign manager David Plouffe sent backers an email today asking them to fill out an online survey on what should come next.
"The inauguration is just 62 days away, and as President-elect Obama and Vice President-elect Biden prepare to take office, they'll need your support more than ever," Plouffe writes.
"You've built an organization in your community and across the country that will continue to work for change -- whether it's by building grassroots support for legislation, backing state and local candidates, or sharing organizing techniques to effect change in your neighborhood. Your hard work built this movement. Now it's up to you to decide how we move forward.
"Thanks to you, this country has an historic opportunity. Electing Barack was the first big step, but there's a lot of challenging and important work ahead. Together, we can keep making history."
