"There is one man who knows and understands that this is the time for bold leadership. There is one man who knows how to create the change.. the lasting change... That you have to build from the ground up. There is one man who knows in his heart that it's time to create one America...not two. And that man is Barack Obama," stated Edwards.

In backing Obama, Edwards says Democratic voters must "come together" to beat Republican John McCain in the fall.

"This is our time to take down these walls, to close our divide and build one America that we all believe in. If you want that, if you believe in that, then join me in helping send Barack Obama to 1600 Pennsylvania Avenue," said Edwards.

Edwards' endorsement comes a day after Hillary Clinton's big win in West Virginia. But most political observers say the race is over and Obama will be the nominee. So Edward's risked being irrelevant if we waited any longer to endorse Obama. Obama is not saying, but is acting like the nomination is his.

On Thursday he returned to Michigan, a state where he didn't even appear on the primary ballot, because party leaders moved up the primary which meant none of the delegates counted toward the Democratic nomination. Obama is courting the labor vote and contrasting himself not with Clinton, but John McCain.

"When John McCain came to Michigan in January and said we couldn't bring back all the jobs that have been lost back to America, he was right. We can't bring back every single job. But where he was wrong was in suggesting that there's nothing we can do to replace those jobs or create new ones," Obama said.

Among Obama's proposals are a 150-billion dollar fund to create clean energy technology jobs and a 60-billion infrastructure improvements fund.

As Obama appears to be cruising toward the nomination, Clinton is using her 2 to 1 margin of victory in West Virginia to make the case to Superdelegates. She's asking undecided superdelegates to give her a new look. The angle: she's the best Democratic option to beat Republicans in the swing states.

"The White House is won in the swing states and I am winning the swing states. I can win this nomination - if you decide I should and I can lead this party to victory in the general election - if you lead me to victory - now!," said Clinton.

Part of Clinton's ongoing campaign strategy is that in many swing states. She's won among whites, women, and voters without college degrees. She translates that as she's the best Democratic Candidate to beat McCain come November. Clinton's best hope for winning is a decision on what to do with Florida and Michigan delegates, states she won but that don't count because party leaders moved up their contests. She says she wants to figure out what to do by month's end, which is before the last primary in early June.

John McCain is campaigning on issues that he thinks will help him in the general election. He's in the Pacific northwest this week talking about global warming, an issue that Democrats have championed over the years. McCain promises that as president he'd use American leadership to lead the world.

"We have many advantages in the fight against global warming, but time is not one of them. Those that argue that you either got a choice between a good environment and a lousy economy ... Or a lousy environment and a good economy, I don't agree with. I think we can do both," stated McCain.
