of the craziest knockouts of all time:

Wilder versus Fury

and Bernie versus everyone.

-(chanting): Bernie! -NEWSWOMAN: This morning,

feeling the Bern.

Bernie Sanders dominating in Nevada.

Sanders not only taking the Silver State

but besting his rivals among Latinos,

winning both men and women,

college and noncollege graduates

and even scoring votes from moderates.

-(chanting): Bernie! Bernie! -I am a U.S. senator,

and I got a big ego, and I appreciate the "Bernie."

But it ain't Bernie. It is us.

(cheering)

Damn, Bernie is really committed to socialism, right?

Even when the crowd is trying to cheer for him,

he wants to share it back with them.

I wonder if he's always like this.

Like, on his birthday, are they like...

♪ Happy birthday to... ♪

He's like, "No, to you. Happy birthday to you."

♪ Happy bir... ♪ "No, to all of us.

"It's all of our birthdays.

"In fact, you should make a wish.

My wish already came true. I got socks."

(laughter)

But yes, Bernie Sanders won big in Vegas,

and I'm not surprised.

If anyone needs free college and free health care,

it's a city full of people

who lost all their money playing slots.

And Bernie won big with all the big Nevada demographics.

That's what made this so impressive.

Young people, old people, white, Latino,

blue, bent, feathered, everybody,

which bolstered his electability argument.

But there's still one sizable demographic

that Bernie hasn't won over,

and it's the other Democrats in the race.

NEWSMAN: With the rise of Sanders,

his opponents are beginning to take him on.

Senator Sanders believes in

an inflexible, ideological revolution

that leaves out most Democrats, not to mention most Americans.

Some believe, uh, that the way to beat Donald Trump

is to be just as polarizing.

NEWSWOMAN: Biden with Kasie Hunt,

dismissing Sanders' efforts

to tie himself to former president Obama.

The way that he talks about it,

you think he and Barack were close buddies.

And you think they were not?

I know they were not.

Ooh! (growls)

"I know they were not."

It's a little weird that the Democratic primary

has become a fight

about who is actually friends with Obama.

'Cause have you noticed? Everyone is dropping his name.

He's in all of their ads, you know?

But he's been silent this entire campaign.

It's almost like Obama is the imaginary friend

all the Democrats have.

You know? It's just like, "I saw Obama today,

"and he told me I'm the bestest candidate

"and that I should be president,

"but nobody else saw him

'cause he hides when the grown-ups come."

(laughter)

But here's the thing. I don't know

if Biden should be attacking Bernie

for exaggerating his friendship with Obama,

especially since Biden has to answer

for some exaggerations of his own.

Joe Biden has recently been telling voters

that he was once arrested trying to see Nelson Mandela

in South Africa in the 1970s

when he was already a sitting U.S. senator.

This day 30 years ago,

Nelson Mandela walked out of prison

and entered into discussions about apartheid.

I had the great honor of meeting him.

I had the great honor of being arrested

with our U.N. ambassador on the streets of Soweto

trying to get to see him on Robbens Island.

I came back from South Africa trying to see Nelson Mandela

and getting arrested for trying to see him on Robbens Island.

He was in prison.

But tonight, The New York Times reviewed all available records

and can't find any evidence

of that arrest actually happening.

Man, this is not a good look for Biden.

Because remember, first, he falsely claimed

he marched in the civil rights movement.

Now he's making up a story

about getting arrested in apartheid, South Africa?

It's weird.

Guy's trying so hard to impress black voters

that next he's gonna be like,

"I was there when T'Challa did the trial by combat.

"I looked Killmonger in the face,

and I told him, 'Cut the malarkey, Corn Pop.'"

(laughter)

Now, although Biden keeps telling this apartheid story,

nobody else on the trip remembers getting arrested,

and there's no proof of it ever happening.

And I'll be honest. As a South African,

I'm personally offended by this.

'Cause Nelson Mandela hated it when people used his name

to make themselves seem more important.

That's what he told me when we were in prison together.

(laughter)

So...

after the Nevada caucus...

(cheering and applause)

After the Nevada caucus,

the Democratic nomination picture is becoming clearer.

Warren and Klobuchar

need a miracle to get back in the race.

Biden and Buttigieg are fighting desperately

to be the moderate alternative.

And as it stands,

Bernie seems to be on a clear path

to winning the most delegates.

And I can tell you now.

When he wins them, Bernie ain't sharing shit.

"It's not us. It's me."
