This just in from CNN:
Edwards has told top advisers about his decision. It is expected he will announce it at a speech in New Orleans, Louisiana, at 1 p.m. Wednesday.
Edwards had amassed 26 delegates in the race for the Democratic nomination.
New Orleans is the same city in which Edwards declared his run to be the 2008 Democratic presidential nominee.
Edwards’ campaign Web site said he was to deliver an address on poverty and work on a Habitat for Humanity project in New Orleans on Wednesday.
Edwards has trailed former first lady Hillary Clinton and Illinois Sen. Barack Obama in the early primaries, including a third-place finish in Tuesday’s Florida primary, with 14 percent of the votes. He also came in third in key races in New Hampshire and South Carolina.
An Edwards aide said that he does not plan to endorse either Clinton or Obama, at this time, but he may do so in the future.
And then there were two. Well, three if you count Mike Gravel.
