Taking the oath of office is a serious piece of business.

And being part of an inauguration has a way of focusing the mind on whats to come. Thats what President Obama meant earlier today when he said, "My fellow Americans, we are made for this moment, and we will seize it – so long as we seize it together."

In the months ahead, were going to be tested, and nothing about the challenges we face will be easy.

So were going to need you with us -- to build support for solutions, to help move the country forward.

Make a pledge to be a part of that effort. Say that youll join us.

As citizens of the United States, were a people who draw strength from our diversity of opinion. We take pride in that.

When we disagree, we debate. And where theres common ground, we act -- even though those solutions may be less than perfect.

But we never stop moving forward. Thats our obligation, the responsibility for which weve been entrusted.

And a duty like that is impossible to fulfill if you act alone.

We need you to step up. Pledge to stand with us, and well reach out to add your voices to the debates in Washington, to work with you to make this country a better place for everyone.

Join us for the next four years, and help make history:
