(END VIDEOTAPE)

JONATHAN KARL, ABC HOST: Good morning.

I'm Jonathan Karl.

George and Martha have the holiday off.

And if you weren't paying attention to presidential politics this holiday, we can't blame you. But while most of the candidates have been quiet, Donald Trump used the holiday to go on a Twitter tirade against rivals on both sides, Tweeting, "Remember when failed candidate Jeb Bush said that illegals came across the border as an act of love? He spent $59 million and is at 3 percent."

And overnight, Tweeting, "Hillary Clinton has announced that she is letting her husband out to campaign. But he's demonstrated a penchant for sexism. So inappropriate."

I've been covering Trump's presidential ambitions from the start, all the way back to 2013, when no one thought he would actually run.

And this morning, a look at the year of Trump.

Our roundtable is standing by with their insights.

And we'll even ask a Supreme Court justice what he thinks of Trump's proposals.

But first, we went on the trail this week for an exclusive interview with the man who has transformed the race for the White House.

(BEGIN VIDEOTAPE)

DONALD TRUMP (R), PRESIDENTIAL CANDIDATE: We are going to make America great again. I love you. I love you. Thank you.

KARL (voice-over): As a presidential candidate, Donald Trump turned the Republican primary into a blockbuster.

TRUMP: I will be the greatest jobs president that God ever created, I tell you that.

KARL: We caught up with Trump this week before a rally in Michigan to talk about the year that was.

(on camera): When you first got in, you were kind of dismissed, you know, maybe he'll be a flash in the pan.

But did you -- even you -- think that you would dominate the field the way you have?

TRUMP: Not to this extent, Jon, and not this quickly. I mean really, it's very quick. I mean we're -- we're doing so amazingly well. And we have such a big lead. And I want to keep the lead, because ultimately, what difference does it make if a -- if you're not going to keep the lead.

But, you know, it's a very strong domination. And it's a very, very big lead. So I didn't think that we would have that. You know, I expected to win, otherwise I wouldn't be running. I like to win.

KARL: You thought you would win the nomination?

You thought you...

TRUMP: I thought I would win. I thought I had a very good chance of it.
