San Francisco is 2/3rds renters, all of whom can vote. You shouldn't pretend that they have no say in how their city is run.
If they want more rentals and more density, they have the power to vote for people who can make it happen. Instead they vote for people who talk a lot about preserving the character of San Francisco.
Everyone can vote? American Samoans, green card holders, various non-citizen immigrants? I thought SF was unusually immigrant rich.
There are a ton of people in SF who are paying sizeable taxes and rents with no vote in these matters. It's quite likely they are disproportionately renters.
