Now, again, Donald Trump is unpopular on almost every issue we asked about.

It's possible that if the economy was fine, they'd still be upset at him over his handling of ICE, for instance.

What we know, though, is that these voters say that the economy is the biggest problem facing the country.

44% of the Trump defectors cite economic issues compared with 24% of other voters.

And we know that they give him really negative marks on his handling of the economy, even though that used to be one of his greatest strengths.

So to me, the economy looks like the most straightforward, central explanation for why these voters swing back against Donald Trump in our poll, even though there are undoubtedly other factors as well.

How far down the affordability rabbit hole do you want to go here, by the way?

Well, standing on the outside of the hole for a second, I mean, I think that most people say that he just hasn't made the country more affordable.

A majority say that...

His policies have made life less affordable.

So he was elected to make things more affordable.

They think it's less affordable.

The tariffs are probably part of that.

Continuing long-term inflation that he's not responsible for is probably part of that.

Medicaid cuts, for instance, is another example of a way in which Trump's policies don't seem like they're making things easier for ordinary people.

Fundamentally, they just don't think he's focused on dealing with the problem that they elected him to address.

A majority of voters say that he's not focused on the issues that they care about most.

Absolutely.

And what it all adds up to, though, is a very low approval rating on his handling of the cost of living.

Only 34 percent of voters approve of his handling of the cost of living, 64 percent disapprove.
