Because it's our job to tell you these things, Barack Obama has posted a video on his website declaring his decision.... to form a presidential exploratory committee.
Obama says that what concerns him most about the current atmosphere in America is the "smallness of our politics." He continues, "Today, our leaders in Washington seem incapable of working together in a practical, common-sense way. Politics has become so bitter and partisan and gummed up by money and influence that we can't tackle the big problems that demand solutions, and that's what we have to change."
To bring the field up to date, former VP candidate and senator from North Carolina John Edwards has declared his candidacy, as have Rep. Dennis Kucinich of Ohio and Iowa Gov. Tom Vilsack. Senators Joe Biden of Delaware and Chris Dodd of Connecticut have also said they will seek the nomination.
Other Democrats mentioned as possible candidates include John Kerry, Al Gore, New Mexico Gov. and former ambassador to the U.N. Bill Richardson, retired Army General Wesley Clark, and the Rev. Al Sharpton.
Oh, and Hillary.
