I think progressives never thought about this because we banked on immigration and demographic change allowing us to win culturally and electorally but the issue is immigrants tend to be overwhelmingly male, that is how Trump won actually he won over a lot of Hispanic,Black,Asian and indigenous men who feel humiliated by a new culture, economy and world.
So what can we do rhetorically and policy wise to win more young men over ?
I think Walz can be that guy, seriously.
Waltz is so obviously fake, insincere, and a typical democrat through and through that the Democrats have zero chance while he is on the ballot for President or Vice President. They need to try and make people forget he exists.
