Tim Walz offers a model of masculinity that is easygoing and joyful, instead of the angry and bitter one Trump and MAGA speak to. And it's making them nuts. So nuts that they think "gross, he cares about women" is a fruitful line of attack.
I was nuts enough to go both to the JD Vance event in South Philly and then to the Kamala Harris/Tim Walz rally later in the day. It was like leaving a bitter divorced man meet-up and going straight to a Taylor Swift concert. Enjoy the contrast!
