President Obama isn't waiting a minute to pass the torch of presidential campaigning to Vice President Joe Biden, a likely 2016 presidential candidate.

Just three hours after both recited the oath of office, Biden issued an email to supporters rich with presidential themes and urgings of help.

Biden may be joined by Secretary of State Hillary Clinton and New York Gov. Andrew Cuomo in the Democratic primaries, but most recent vice presidents who try to follow their boss win the Democratic nomination.

Good afternoon --

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 what's to come. That's 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, we're going to be tested, and nothing about the challenges we face will be easy.

So we're 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 you'll join us.

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

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

But we never stop moving forward. That's our obligation, the responsibility for which we've 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 we'll 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:


Vice President Joe Biden
