From ABC News, it's THIS WEEK.

Here now, chief anchor George Stephanopoulos.

GEORGE STEPHANOPOULOS, ABC HOST: Good morning.

As we come on the air this week, Bernie Sanders and Ted Cruz both on a roll. Sanders taking the Wyoming caucus, his eighth win in nine contests. Cruz sweeping all the delegates in Colorado yesterday, after that big win over Donald Trump in Wisconsin.

The chances of a contested convention in Cleveland now higher than ever. We're going to have more on that ahead, but we begin with the Democrats.

Senator Sanders is here live in studio.

New York ground zero now.

And ABC's Cecilia Vega starts us off on Broadway -- good morning, Cecilia.

CECILIA VEGA, ABC NEWS CORRESPONDENT: George, that's right.

Good morning to you.

This battle right now is all about New York. It is an Empire State showdown and the fight happening on these streets right now is more heated than ever.

(BEGIN VIDEO CLIP)

SEN. BERNIE SANDERS (I-VT), DEMOCRATIC PRESIDENTIAL CANDIDATE: News bulletin, we just won Wyoming.

(APPLAUSE)

VEGA (voice-over): With his latest win, Bernie Sanders is on a roll, coming out on top in seven of the last eight states. But despite his 12-point Wyoming victory, the Vermont senator walked away with the same number of pledged delegates as Hillary Clinton. And that shows the uphill battle ahead. With the super delegates factored in, those delegates free to support any candidate at the convention, Sanders trails by nearly 700. His campaign is now, instead, focused on the much closer contest for pledged delegates, those delegates won and lost in state primaries. Clinton's lead there much smaller, 250.

Sanders says the contest is far from over.

SANDERS: We are on the way to pulling off the biggest political upset in the modern history of America.

(APPLAUSE)

VEGA: And his team is threatening a convention fight if Clinton doesn't clinch the magic number of pledged delegates before the summer showdown.

The most delegates up for grabs so far, 247, in New York, the next state up. The fight here nastier than ever -- a war of words over who's qualified to be president.

(on camera): You said, quote, unquote, "She is unqualified," and this morning, you said she's qualified. So which is it?

SANDERS: Well, in a sense, it's both. If you vote...

VEGA: It can't be both, can it?

SANDERS: Yes, it can, in this sense.
