US: Crime rates in cities mainly a Democrat thing

I made the above charts from the data on Wikipedia. Violent and property crime for the top 20 cities in the US and the party affiliation of their Mayors. 

I’m reading San Francicko, by Michael Shellenberger, himself an ex radical socialist, admirer of Noam Chomsky, etc... now turned critic. He takes on this issue. Why so much crime, homelessness, hopelessness in progressive-run cities? Many of which have been progressive-run for decades. 

In the US, violent and property crime has jumped in the last two years. After the George Floyd death by police, the subsequent riots, and then the pandemic. And it’s jumped an average of 44% during the Biden administration. 

Most crime affected cities are run by Democrats -- 85% to 15%. You could object that that’s because most cities in the US are run by Democratic mayors. And that’s correct. But that figure is 60-40 for the top 100 cities. So there’s still 25 percentage points more violent crime to account for, that’s down to Democratic mayors. 

If you want clean cities, reduced homelessness, less violent and property crime, safer neighbourhoods, and you live in the US and have a vote, on the odds alone you’d have to vote Republican. If you care about public order and safety.
