From Obama to his voters: "How this happened"

Dear Arnaldo,

I'm about to head to Grant Park to talk to everyone gathered there, but I wanted to write to you first. We just made history. And I don't want you to forget how we did it.

Our records show that you live in California's 23rd district.

You made history every single day during this campaign -- every day you knocked on doors, made a donation, or talked to your family, friends, and neighbors about why you believe it's time for change. I want to thank all of you who gave your time, talent, and passion to this campaign.

We have a lot of work to do to get our country back on track, and I'll be in touch soon about what comes next. But I want to be very clear about one thing... All of this happened because of you.

Thank you,

Barack
