From The New York Times, I'm Michael Barbaro. This is The Daily.

Today, new data is challenging the popular portrait of the Trump voter

and revealing why it's the Trump voter we don't talk about,

who may determine the outcome of the mentors.

It's Friday, August 10.

Nate, can tell us about this poll and why you're interested in it?

It's a pretty novel survey. Most polls you'd call 1,000 people you're done with them.

You instead has recruited several 1,000 people to take their polls every month.

What they did was they asked people in November 2016,

did you vote for the president and how do you feel about it?

They went a step further. They went and matched their panelists to official voter records

that indicate whether someone voted or not.

Now flash forward to 2018, they went back to those same people and asked,

how do you feel about the president today?

So you have a great picture. You both have a really good account of how people felt in 2016

and we can ask the same people how they feel about the president today.

So most polls just go pick up a group of people like 1,000 people,

ask them a question and kind of discard them.

And then the next poll asks a different group of people and so on and so on.

This poll has been kind of more faithful to the same group of people.

Yeah, and that's nice because you know that changes you've seen the poll

are because of people changing their minds, not changes in who you're asking.
