As New Jersey Gov. Chris Christie gets ready to deliver the keynote address at the Republican National Convention, he tells ABC's "Good Morning America" that he'll keep an eye on Tropical Storm Issac, but his speech hasn't changed from its original version that much: 

“I’ll be talking about the New Jersey experience and what that means for the country, what it can mean and promise for the country. They’ll be some other stuff I’ll be talking about too. But I’ll be ready when I walk out on that stage tonight,” he said.

“I think that if the American people watch tonight and leave the speech by saying, ‘Yup, that’s him, that’s who I’ve heard about. He seems genuine to me,’ then think I will have done my job for me and if they say I like the vision he’s laid out for the country and for his party for the next four years, then I will have done the job for my party and my country,” he said.
