Vice President Kamala Harris has selected Minnesota Gov. Tim Walz as her vice presidential running mate, according to three sources with knowledge of the pick, adding a popular Midwestern state executive to the Democratic ticket as the party gears up to hold onto key Northern battleground states this fall.

In picking Walz, who’s in his second term and also served 12 years in Congress, Harris will have as her No. 2 someone with a proven record of winning over white working-class voters in Rust Belt states while also boasting a robustly progressive record.

Democrats will hope that mix of attributes helps a Harris-Walz ticket shore up support in the onetime “blue wall” states of Wisconsin, Pennsylvania and Michigan — longtime Democratic strongholds at the presidential level that Donald Trump flipped in 2016 and Joe Biden flipped back in 2020. This year, they’ve been seen as Biden’s, and now Harris’, most viable path to victory.

Walz, 60, had initially been viewed as a long shot in a field of vice presidential contenders that included rising party stars, some of whom have been mentioned as future presidential candidates, including Pennsylvania Gov. Josh Shapiro.

Now Harris has chosen a governing partner who has leaned in at times to a folksy, Midwestern reputation while also proving to be a reliable attack dog against Trump.

Walz’s experiences earlier in his life, as a public school teacher and a member of the Army National Guard, could also buttress his ability to speak to different voting blocs — including veterans and organized labor — that Harris will need to win in November.

Walz, a Nebraska native, enlisted in the National Guard when he was 17 and served for more than two decades, with both domestic and overseas deployments. He later was a high school social studies teacher and football coach in Mankato, about 80 miles south of Minneapolis, before he won a congressional seat in a largely rural and agricultural district in 2006.

He represented Minnesota’s 1st District for 12 years before his successful run for governor in 2018. A 1995 reckless driving arrest in Nebraska, during which, an officer said, Walz had failed a sobriety test, came up in his campaigns for House and the governorship, but he was elected anyway. Walz called it a “gut check moment” in an interview with the Minneapolis Star Tribune in 2018, saying he stopped drinking afterward.

Walz’s allies have spoken frequently about how his background representing rural communities is much needed in the party, noting that he won re-election in a red-trending district — one that was about evenly divided in 2012 but swung heavily to Trump in 2016 — and could help Democrats compete for some moderate or conservative voters skeptical of Trump this time around.

Walz also had the most Capitol Hill experience of anyone on Harris’ reported short list, with relationships in Congress that could help a new president move a legislative agenda.

As governor, Walz has overseen a bonanza of progressive policy accomplishments — particularly during his second term, during which Democrats have also controlled both chambers of the Legislature. 

He has signed laws protecting abortion rights, legalizing recreational marijuana, restricting gun access and providing legal refuge to trans youths whose access to gender-affirming and other medical care has been restricted elsewhere. Progressives elsewhere have pointed to Minnesota as a case study in how to effectively use the power of a legislative trifecta to achieve policy priorities.

Walz also enacted laws expanding paid family leave, banning most non-compete agreements, providing universal school meals for students and capping the price of insulin in Minnesota (three years before Biden did it nationally) — a list of legislative wins his colleagues and supporters have said would translate nationally.

Walz doesn’t have the same degree of name recognition as many of his presumed competitors to be Harris’ running mate, though he spent a year leading fundraising efforts for Democratic governors as chair of the Democratic Governors Association. In recent days, Walz has turned up the publicity dial, trying out attack lines against Trump and Sen. JD Vance in a slew of media appearances.

In a late July interview on MSNBC’s “Morning Joe,” he ripped Trump and Vance as “weird,” gaining wider notice. Harris herself began using the “weird” line almost immediately.

Walz also explicitly used his media appearances to attack the GOP ticket by playing up his strong cultural ties to the middle of the country — and to demonstrate to Democrats how he would intend for the party to win over those voters.

“What I know is that people like JD Vance know nothing about small town America,” Walz said on MSNBC’s “Morning Joe” on July 23. “My town had 400 people, 24 kids in my graduating class, 12 were cousins. And he gets it all wrong.”

“It’s not about hate. It’s not about collapsing in. The golden rule there is mind your own damn business,” Walz said, adding that Republican “policies are what destroyed rural America. They divided us. They’re in our exam rooms. They’re telling us what books to read.”

“And what I think what Kamala Harris knows is bringing people together around the shared values, strong public schools, strong labor unions that create the middle class, health care that’s affordable and accessible, those are the things,” Walz said.

Picking Walz doesn’t come without risks. While his selection underscores Democrats’ effort to aggressively go after Midwestern voters, he doesn’t bring a specific battleground state advantage: Minnesota hasn’t gone red in a presidential race since 1972.

In addition, as Walz’s stock has risen in recent days, critics have reintroduced questions about his governing record. They include concerns over a delay calling in the National Guard as protests engulfed Minneapolis following the murder of George Floyd by city police officers in May 2020, as well as the fact that the biggest pandemic fraud case in the U.S. happened under his watch.

Another presumed liability for Walz’s VP chances early on had been his role as a co-chair of the Democratic National Convention rules committee — a job that, in the chaotic days after Biden dropped out of the race, led him to help Harris quickly become the party’s presumptive nominee.

Any potential criticism over a conflict of interest was largely rendered moot when precisely zero high-profile competitors challenged Harris for the nomination.

Walz told reporters that “anybody [who] wants to put their name in” to be nominated” can do so.
