Welcome to the Beat everyone. I am Ari Melder and the DNC is concluding its

delegate voting late today with Kamala Harris on track to become the party's

official nominee. This is the official developments that come after she had passed the number of delegate votes she needed Friday.

And it comes as the New York Times is reporting Donald Trump is now shook.

Harris is surging in a language that Donald Trump speaks. Big rallies, big

ratings, and these gripping made-for- TV images. The New York Times has this new article out that reflects what's going on in Trump

world and will probably be noticed in Trump world. What's rattling Trump? The headline reads,

the size of Harris's crowds. Her star turn on the stage across all of national politics

and the way she's being received has quote unsettled Mr. Trump and in Washington there are Republican senators who are speaking anonymously

for obvious political reasons, but still who want to share what they see as the concern

that Trump has been completely caught, quote guard by Kamala Harris's strength.

Quote, I think she's more formidable than Republicans give her credit for, says one of these Republican

senators, quote, it's going to be a short election that favors her.

It's going to be a sprint that helps her.

And this enthusiasm that we're seeing

that's been covered here on MS NBC and in local papers and in all across the

internet the kind of extravagant sometimes excitable crowds is gone beyond just

Democrats it's visible across these events.

If you've got something to say,
