GEORGE STEPHANOPOULOS, ABC HOST: And what a week it has been. Super Tuesday, that stunning Republican debate. And with votes in five states Saturday, the race for president may now be taking a new dramatic turn.

For the GOP, a big night for Ted Cruz. He trounced Donald Trump in the Kansas caucuses, beating him by 25 points, surprised Trump in Maine, too, with 46 percent, Trump at 33, John Kasich and Marco Rubio far behind there.

Trump did get two wins in his southern stronghold, taking Louisiana primary with 41 percent, but Cruz just three points behind.

And it was a tight finish in Kentucky, Trump at 36, Cruz at 32.

Add is all up, and Cruz won more delegates Saturday than Trump and tightened the gap in the overall race. Trump is now at 378, Cruz 295, Rubio 123, Kasich trailing down at 34.

For the Democrats, Bernie Sanders swept the caucus states, winning Kansas handily with 68 percent of the vote, Clinton got 32. He came out on top in Nebraska, 57 for Sanders, 43 for Clinton.

But it wasn't even close in Louisiana. Clinton beat him 71 to 23. And that added to her delegate lead last night. She is now up overall by more than 200 even before you count those Democratic super delegates, which give her an overwhelming margin.

So how can Bernie Sanders come back? He is here now to tell us. Senator Sanders, thank you for joining us this morning.

And you were admirably candid last Saturday after South Carolina. You said you get decimated. What's your take on last night?

SANDERS: Well, I think we did great overall yesterday. We won, as you mentioned, by over two to one in Kansas, we did very well in Nebraska. There's going to be a caucus in Maine. And if the turnout is high, I think we're going to win there. That would mean that we'd have won eight primaries and caucuses.

And what impresses me very much, George, and what I mean when I talk about a political revolution, in Kansas they had the largest voter turnout in their caucus history. That was the case in Colorado where we won as well.
