Every day, I see Barack make choices he knows will affect every American family. That’s no small task for anyone — and more proof that he’s earning every last one of those gray hairs.

This has been a busy week in Washington, but today happens to be Barack’s 50th birthday. I’m writing to you because this year, the girls and I would like to do something a little different.

I’m asking friends and supporters of this campaign to wish him a happy birthday by signing his card, and sharing why you’re on this journey with us.

Your names and notes will become part of a book that tells the story of this campaign — who’s building it, why we’re in this thing, and what he means to us. We’ll deliver a copy to Barack and send one to our campaign offices across the country.

I’ve known Barack for more than 20 of his 50 years, and we’ve been through quite a lot together.

It still amazes me that no matter how many decisions and distractions he’s faced with every day, he’s always able to focus on the bigger picture. One way he does that is by making time for stories and letters from people like you — because he knows that this job isn’t about him, but about the millions of folks around the country he’s fighting for.

This next year will challenge us all to work harder than ever before, but the crucial thing is that you’re here now, early on, helping to build this campaign.

I know that, like Barack and me, you have your own reasons why, so I hope you’ll take a moment to sign the card and share your story with him and other supporters of this campaign.

Thanks for being a part of this,

Michelle
