It would be overly speculative to argue that Jackson MS, one of the most conservative 100k+ cities in the US, has a spectacular murder rate compared to SF because medical care is so good in SF.
Jackson, MS is in Hinds county, which voted 73.4% for Biden in 2020, 71.1% for Clinton in 2016, and 71.5% for Obama in 2012. There hasn't been a single Republican mayor of Jackson in the Post-WW2 period. It's strange to call someone else's comment overly speculative when yours is flat out incorrect.
This is out of the 100 most populous of the cities that have data in the FBI Uniform Crime Reports system.
Here are the top 5 in each of these categories.
Murder etc: St. Louis, Baltimore, Detroit, New Orleans, Baton Rouge
