Hillary Clinton: 'I'm in! And I'm in to win!'

Hillary Clinton announced earlier today that she will be running for President. Via Clinton's website:

I'm in. And I'm in to win.

Today I am announcing that I will form an exploratory committee to run for president.

And I want you to join me not just for the campaign but for a conversation about the future of our country -- about the bold but practical changes we need to overcome six years of Bush administration failures.

The AP writes:

Clinton's announcement, days after Sen. Barack Obama shook up the contest race with his bid to become the first black president, establishes the most diverse political field ever.

Clinton is considered the front-runner, with Obama and 2004 vice presidential nominee John Edwards top contenders. New Mexico Gov. Bill Richardson, who would be the first Hispanic president, intends to announce his plans on Sunday.
