In case you somehow haven’t noticed, manhood is on the ballot.

Even before President Joe Biden stepped aside to let Vice President Kamala Harris step up to be the Democrats’ presidential nominee, insiders from both parties were calling this the “boys vs. girls election.”

And even before the Republican National Convention opened in Milwaukee last month, spokesmen for Team Trump were telling reporters they hoped to contrast “weak vs. strong” as their social media message — and present a stage show as testosterone-fueled as a Super Bowl.

And, hard on the heels of Trump’s MAGAs, along came the Democrats in Chicago to challenge the GOP’s hyper-masculine chest-thumping with their own Hollywood star-studded post-Biden challenge to the polling gender gap.

Their message: reproductive rights-dominated inclusivity across all racial and gender lines. Rarely has an election campaign been so sharply and unashamedly defined by the gender gap.

Of course, considering how the last time the race was so sharply defined by the gender gap may have been 2016, when Hillary Clinton lost to Trump, it was prudent of Harris to pick Minnesota Gov. Tim Walz as her running mate.

In contrast to the famously bombastic style of Trump, Walz presents what feminists have called “positive masculinity.”

He’s also been predictably slammed by attack campaigns, to limited effect.

Walz spent 24 years in the Army National Guard. However, he never served in an active combat zone. Nevertheless, at a public meeting about gun violence in 2018, he said, “We can make sure that those weapons of war that I carried in war is the only place where those weapons are at.”

His use of the phrase “in war” on this one occasion was seized upon by Trump’s running mate, Ohio Sen. J.D. Vance, a Marine veteran who served in Iraq, although not in combat. The Harris-Walz campaign responded that Walz “misspoke.”

Frankly, as a Vietnam War veteran who also missed actual combat, I honor both men for serving their country. That service, too, offers an example of positive manhood.

Positive masculinity is an assortment of attitudes and behaviors that build on the qualities positively associated with traditional masculinity, while avoiding its negative aspects. Those include thoughtless aggression, domination and violence — behaviors that victimize women and girls.

One particularly striking anecdote from Walz’ past might well have sealed the deal in his favor. When he was asked in 1999 to be faculty adviser for his southern Minnesota high school’s first gay-straight alliance club, Walz, then a geography teacher and football coach, agreed to do it.

The meaning and value of manhood is an endlessly debated topic, as it should be. It should not be endlessly exploited. Honor, courage, leadership, honesty, integrity and fairness are just a few of the qualities to associate with positive manhood. It’s easy to think of more. Unfortunately, it can be a lot harder to live up to them.
