Cities, counties, and states are not monolithic entities. There is always a mix of competing interests. This means even in Seattle there are a lot of conservatives. These conservatives own a lot of capital.
Trust me bro, it is most definitely a wedge issue for conservatives. I have been to tons of city and county meetings. It is not liberals calling to imprison the homeless. Guess who wins out. Fucking capital everytime.
You ever had the chance to live in a rural area and hear what they think of homeless people?
The right has been literally demonizing the homeless for thirty or more years now.
They made homelessness a fucking partisan issue. You know about the bleeding heart liberals wasting money on drunks and drug addicts. Their messaging has always been clear, not in my back yard.
The Democratic party is also no were near monolithic either. For sure there are some who blame homelessness on character defects or lack of ambition but the majority do not.
Conservatives are a loud minority voice who have capital to back them up. It is amazing how the government bends over anytime "economic" interests come to play.
This issue is really complex and owes a lot to a social contract we broke when we deinstitutionalized mental hospitals in the 50's and 60's.
