The left leaning politics of someone like Alexandria Ocasio-Cortez is electable in an urban district like central New York City.
She would be less electable from the sprawling suburbs across USA where most people live. The suburbs full of swing voters.
Even less electable in rural America; though Bernie Sanders, from the rural state of Vermont, is a notable exception.
I think, if we want politics to go more to the left, we need to strive toward more urban lifestyles. This can be seen here in Whatcom County where our urban center; Bellingham, tends to vote more liberal than the rest of the county.
I would guess that things like high gas prices become less of a political liability in places where commutes tend to be shorter.
I recently heard about the concept of the 15 minute city. That's the concept of living within a 15 minute commute to most needs; such as work, shopping and social life.
Face to face social interaction can have an effect on politics, I would guess. It's more likely in the 15 minute city.
Even if a metropolitan area is too large to be crossed by a 15 minute trip, the concept applies to how far one's needs are from their residence. Mixed use zoning can help with that by allowing a mix of densities, jobs and services in each area of the city.
In my case, I'm a 15 minute bike ride from downtown Bellingham so just about all my needs can be met within a 15 minute radius of my residence. This neighborhood also has bus service which, I think, is on an every 15 minute schedule.
