MARTHA RADDATZ, ABC NEWS CORRESPONDENT: Let's say Hillary doesn’t draw this kind of crowd.

DONALD TRUMP (R), PRESIDENTIAL CANDIDATE: Not even close.

UNIDENTIFIED MALE (voice-over): We are right there with him in the chopper, with the crowds.

What he's doing now to hold the lead while Carly Fiorina and Ben Carson surge in the polls. They're here live.

And Hillary's new headache: her email firestorm growing. The latest on the FBI investigation.

Plus the big buzz that Al Gore and Joe Biden could be eyeing a 2016 run.

From ABC News, a special edition of THIS WEEK with Martha Raddatz reporting live from the Iowa State Fair begins now.

(END VIDEOTAPE)

RADDATZ: Good morning. Organizers say 1 million people will visit the Iowa State Fair. But it's just one person who managed to steal the show this weekend. We were with billionaire and GOP front-runner Donald Trump every step of the way, Trump front and center from the start.

(BEGIN VIDEOTAPE)

TRUMP: You're going to love me in terms of immigration and illegal immigration. We're building a wall. It's going to be a wall that is not -- nobody's going through my wall. Trump builds walls. I build walls. I don't think I've made mistakes. I mean, every time somebody says I made a mistake, they do the polls and my numbers go up.

So I guess I haven't made any mistakes.

And you want to know what things am I going to do different for this -- almost everything because that's what has to happen. Everything we do is wrong. The military, we're not taking care of the military, not taking care of our vets. We're not taking care of our country. We're not taking care of our finances. We're not taking care of our trade deals.

When was the last time you saw this country have a victory?

We don't have victories.

RADDATZ: This morning, so many new questions about 2016, can Donald Trump keep up this momentum?

How will his opponents step out of his shadow?

We'll ask two top contenders shortly.

What does all of this mean for a race unlike anything we have seen before?

(BEGIN VIDEOTAPE)

RADDATZ (voice-over): Even before his helicopter the landed Donald Trump was the star attraction at the Iowa State Fair this weekend. Forget the livestock and the fried-on-the-stick delicacies. It was Trump, Trump, Trump.

When the billionaire candidate finally descended from the sky, we joined a few lucky kids for a ride better than any roller coaster.

RADDATZ: This is pretty exciting?

UNIDENTIFIED MALE: Yes.

RADDATZ: You don't think this is a little much?

UNIDENTIFIED MALE: No.

RADDATZ: It's very Trump, right?

UNIDENTIFIED MALE: Yes.

TRUMP: It's me. I am who I am. It's good for the kids. The kids love it.

RADDATZ: But you know where we were four years ago here, the people at the bottom of the polls didn't eventually do so well.

TRUMP: Who was here? Who was?

RADDATZ: Well, you had Michele Bachmann and --

(CROSSTALK)

RADDATZ: -- and Rick Santorum --

TRUMP: They're not me. They're not me.

I have had a lot of fun. You know, I have never run for office before. I love what's happening.

RADDATZ (voice-over): His brashness, outspokenness, clearly the draw here.

RADDATZ: Would a President Trump be the same as Candidate Trump with foreign leaders?
