See NIMBYs all down the west coast. I bet 90% of city dwelling homeowners would identify as “democrat or further left”, but are very conservative with the character of their neighborhood.

In my experience the bulders and tradesmen who are more right-wing have more to gain from allowing more and faster construction and are more interested in removing laws and restrictions.

A lot of this comes from the attitude in the 60s and 70s where the liberal strategy was to sue the government to stop them from destroying the environment. People from that era saw the smog and the flammable rivers and are generally against development , even though today’s development processes are starkly different from back then.
