The Fall Campaign is here and for all the talk about republicans, it is now clear there is going to be a hard fought race for the democratic president ial nomination, as well. Joe biden sure looked like a candidate as he ran along a labor day parade route in pittsburgh shaking hands, kissing babies and maybe even dropping an unintentional hint in a speech to union workers. Back in delaware if you make someone stand on a hard floor for more than 15 minutes you lose all their votes. I dont want to lose your i dont want to lose your friendship.

Reporter but the once prohibitive frontrunner is looking more and more vulnerable. Bernie sanders continues to gain ground. Hes now up by 9 points in New Hampshire. His widest lead yet.

Reporter she absolutely is. She says no, she will not apologize. Essentially because she has nothing to apologize for.

We met this mother desperate to get her son to germany for medical care. So much misery here. Everybody has a story. At times the anger here has boiled over. But overnight a new plan, officials setting up a Processing Center on this soccer field which they say will run 24 hours a day until they can decon jest this island. And just look at the gratitude when that mom we met finally gets her papers. And this morning, more refugees are boarding more boats here in the port. The process appears to be going more smoothly at this point but bear in mind this is just one more step in what remains a long and order use journey ahead for these people. George. It sure does.
