Here’s a video reminder:

Obama won the presidency precisely because of his experience as a grass-roots organizer. His campaign harnessed the power of the people — and the Internet, the most democratic medium ever conceived — to inspire a nation and build a populist political machine.

This represents nothing short of a sea change in American politics and hopefully in how the nation governs itself. I think Obama realizes that he is now the nation’s Community Organizer in Chief.

From his victory speech:

The road ahead will be long. Our climb will be steep. We may not get there in one year or even one term, but America – I have never been more hopeful than I am tonight that we will get there. I promise you – we as a people will get there.

There will be setbacks and false starts. There are many who won’t agree with every decision or policy I make as President, and we know that government can’t solve every problem. But I will always be honest with you about the challenges we face. I will listen to you, especially when we disagree. And above all, I will ask you join in the work of remaking this nation the only way it’s been done in America for two-hundred and twenty-one years – block by block, brick by brick, calloused hand by calloused hand.

The campaign does not end here — it only shifts its focus to fulfilling the promise of change.

To the hundreds of thousands of volunteers, including myself and many friends who pounded the pavement in the closing days: Don’t stop now. Stay active. Organize. Call and write your Congressional representatives as Obama pushes legislation to effect changes we desperately need.

Obama needs our help now more than ever.
