Walz was a hit in the Midwest. Will he appeal to Florida voters voters?

Walz is largely unknown outside his home state.

He has more limited experience with the southern border, a crucial issue in this election but especially in Arizona, where the campaign will make an appearance on Friday as part of its battlegrounds tour. It’s the home state of one of Harris’ rejected contenders, Sen. Mark Kelly.

And some Sun Belt Democrats fear that Walz tips the ticket into more progressive territory that could be hard to sell to more moderate voters across the suburban and rural South and Southwest.

“Walz is a question mark” because he is untested with swing voters outside of the Midwest, former Democratic Rep. Carolyn Bourdeaux told POLITICO.

“The challenge is going to be for Harris to figure out a way to win over those [swing] voters, and I don’t think Walz is going to do the trick.”
