As for running for president in 2028 I just don't see it. I think Walz would be great but frankly I don't see any white male candidates getting the Democratic nod. He would make an interesting VP candidate though; governor, congressman, teacher, 24 years in the National Guard. My guess is he does try for a third term as governor in 2026.
FWIW if you are looking for a Minnesotan to run in 2028 I think Amy Klobuchar gives it another shot. Probably won't be any more successful than in 2020 but she is very ambitious and it would probably be her last shot.
But wouldn't he be a good running mate for, say, Kamala Harris? She would almost certainly need to pick a white man, and Walz is a white, male, popular governor from the Midwest. Plus while Walz has at least some crossover appeal, he shouldn't turn off progressives either, considering how successful Walz has been in enacting progressive legislation in his state.
EDIT: Actually Walz may not be as popular as he once was, obviously conservatives would not be happy about the progressive policy that Walz has successfully enacted. But Tims Walz should still appeal to progressives, and he did have at least enough crossover appeal during his gubernatorial victories (especially 2018) to outperform Clinton and Biden by quite a bit in the more rural parts of Minnesota.
