Dig into the data all you want. If you dig deep enough, you'll most likely find what you're looking for...
Anything political like this is going to have competing "sources of truth" which are largely funded by Super PACs and essentially just arms of political parties.
Either party can "show you the data" now to come to whatever conclusion they want.
This is a useful gambit to game all the people who claim to want to be "data-driven".
Sometimes, it's useful to zoom out to a 1000 foot view and simply observe that something is clearly broken, and the current solution does not appear to be making it less broken.
Maybe this is something everyone can agree on - but, that won't be very helpful - as there's unlikely any changing solution that both parties will agree on.
I'll simply note - at the 1000 foot view - there are 115,000 homeless people, and $17B was spent on them.
That's $147k per person. And all that happened is the problem got worse at MUCH faster rates than it did in almost every other state in the US, nearly all of which are spending much less on the problem.
Draw your own conclusions...
