Its both. That's the problem. In my neighborhood, the construction of any market rate housing will be blocked by Hillary voting land-owners and single family home owners and card-carrying Bernie Bros mad that a private developer even gets to set foot in the city.
It's this alliance that has basically blocked housing in most metro cities.
When it comes to 100% affordable housing, yes the Hillary voters are on their own, but those are like 1-2 headline causing projects. For every affordable housing project there are 10 market rate housing projects that never even see the light of day.
