From the New York Times, I'm Michael Barbaro.

This is the day.

Today, Bernie Sanders enters a crowded field of democratic presidential candidates.

How those candidates who agree on so many social issues are fighting to distinguish themselves

in order to beat President Trump?

It's Wednesday, February 20th.

Good morning, Lawrence!

I stand here today to declare that I am a candidate for President of America.

I stand here for you today to announce my candidacy for President of the United States.

To announce my candidacy for President of the United States.

I'm filing exploratory committee for President of the United States of the United States.

I'm running for President because I want to address these issues.

Hi, I'm Bernie Sanders. I'm running for President.

And I'm asking you today to be part of an unprecedented grassroots campaign.

And we are going to do this again.

Alex Burns, what does Bernie Sanders' announcement mean for the 2020 presidential race?

Well, it really means that now we have a full spectrum of democratic candidates running from sort of quasi-Marxist to a validly moderate.

That might sound like we now have this messy, shapeless field, but in reality, they are all basically debating the same central question,

which is, who has what it takes to beat Donald Trump?

All the candidates, all the voters from different wings of the party basically agree that that is the overarching theme of this primary.

They just all have different answers to that basic question.

And as these democratic candidates debate visions for beating Trump, I have to imagine that is a calculation about moving left.
