Tim Walz Is Too Good at This

Minnesota Gov. Tim Walz is the Democratic vice presidential candidate for Sen. Kamala Harris .

The Minnesota governor has been a popular figure in the Democratic presidential race.

He has been an instant sensation since Harris picked him to be her running mate.

CNN 's John Sutter visited Walz 's campaign events across four states to get a closer look at his populist persona.

Tim Walz is a much more approachable avatar for would-be Harris supporters, those classic rockers, tellers of dad jokes, and football-watching wearers of Taylor Swift friendship bracelets.

He is like a midwestern version of the Car Talk guys, except that Click and Clack could never pivot as seamlessly as Walz can into a discussion of, say, the evils of Project 2025 .

David Gergen : Veteran Walz watchers can grow weary of his practiced yokel act.

Gergen says Walz has benefited from the frenetic pace of contemporary politics.

He says it's a mystery why Walz hasn't done national media, especially given how effective he was over the summer .

But how will this translate against the cool, cerebral vitriol of Vance ? Gergen asks.
