The media have spent weeks hyping the Kamala coup as a fantastic move that has changed the race.

And it has.

But a CNBC poll raises a question about whether the Dems also traded older voters for younger voters.

After the replacement of President Joe Biden with Harris, an assassination attempt on Trump and the Republican convention, Trump’s 48%-46% lead is within the CNBC survey’s margin of error and unchanged from the 45%-43% lead Trump held against Biden in the NBC News July Survey. While the head-to-head competition remains the same, there have been dramatic but offsetting changes beneath the surface for both sides that have kept the race even.

The most dramatic shift: 81% of Democrats are satisfied with Harris as their nominee, compared with just 33% who were satisfied with Biden. But that was partially offset by a 9-point gain among Republicans who are satisfied with Trump as the nominee, bringing his number to 80%.

Interest in the election rose 3 points for Democrats, but it rose 2 points for Republicans. Young voters showed far greater support for Harris than they did for Biden, backing the vice president now by 10 points, compared with backing Trump by 2 points in the NBC July poll. That was offset by a big swing of 12 points among voters aged 35-49 toward Trump. The age group now supports Trump by 9 points.

These are really disastrous numbers.

Kamala is coming off the best weeks of her campaign and the general race is neck and neck. (Which if you’re a Dem is bad.)

But the demographics are where things get interesting.

Trading voters 35-49, who are likely to vote, for younger voters, who are much less likely to, is a really bad deal.

It’s no surprise that with the amount of social media hype, paid social media influencers and culture war noise, Kamala is doing well with younger demos, but what exactly is it about Kamala that was so off-putting to 35-49 year old voters who previously supported Biden?

The answers are one and the same. Kamala’s public persona is goofy and unserious. She may be turning on the younger crowd, but she’s turning off people who are actually grown up, have jobs and families.

She’s losing Biden voters and gaining TikTok viewers.
