"In less than 24 hours, voters in South Carolina will head to the polls.
Before they do, I wanted to show you a bit about what kind of campaign we're running here.
When Michelle and I talked about my running for president, one of the core goals we both had for this campaign was to leave the political process better off than we found it.
Here in South Carolina, a state with a history of some pretty divisive politics, ordinary people have challenged conventional thinking about the process and built a statewide organization based on local community organizing and neighbor-to-neighbor contacts.
Our supporters -- men and women of all ages, races, religions, and backgrounds -- have come together around the idea that we are one people, invested in each other and in our common future."
No matter what the outcome tomorrow, our work here will have a lasting impact on those communities and on the Democratic Party for a long time to come.
We're seeing the same story play out across the country as grassroots supporters in 22 states prepare to cast their votes or turn out to caucus on February 5th."
I believe more strongly than ever that this movement for change can do more than just win an election. Together, we can transform this country."
Here's one video of organizing in South Carolina:
