Sure, none of this stuff happens in a vacuum. We can go back years and even decades within the state to see the build up to today and Republicans have played a role in that. But on the whole Democrats have often dominated the state and pushed for policies (one can argue they were all good/correct policies) that have greatly increased the cost of living in the state and created the off the charts housing costs so it's not shocking we see the level of homeless we do.
And as I mentioned earlier ITT, we passed a $1 billion+ bond in SF to help house the homeless but we can't get approval to build any of the housing because no one wants it around them. It's epitomizes why we have the problem we do here.
