It is almost comical how you want to blame those evil 'conservatives' for this - I guess that makes it easy for democrats to have excuses about why they haven't solved the problem in places where they 100% control the statehouse and legislature and the purse strings.
If liberals/democrats were truly in favor of public housing, then places like California would have a surplus of housing options available for everyone - or are you somehow suggesting that even though conservatives that cannot even come close to winning an election in CA, that they still somehow control all the levers of public policy?
