Thank you for taking this seriously and doing some research. I’m going to spoke a few holes in your conclusions, though.
Firstly, I’m sure you noticed that the vast majority of cities fall under the Democrat column. Of the top 50 cities by population, only 11* have are Republican mayors. Republicans should examine why it is that when large groups of Americans live in close proximity they tend to favor a Dem.
*Actually it should be counted as 10 because the Dallas Mayor switched his party affiliation after he won reelection - and cannot run for another term.
Big cities in the U.S. tend toward the liberal side of the political spectrum, even when they’re within conservative states (residents of Austin sometimes joke that their city is “an island surrounded by Texas”).
Secondly, it is difficult to make clear conclusions about this because of the variations of city management structures. You cite Dallas as your second example of a Republican run city, yet the council-manager system there means that the position of mayor is technically non-partisan. And, as I pointed out above, he was a Dem when he was elected anyway. Dallas county is solidly democratic.
A third consideration is population size, which varies widely in this list. I will note where each city appears in a top 100 ranking by population so we can note that.
Lastly, it looks like you only picked up property crime rates, although I’m not sure where your table came from. I will list both as violent crime/property crime just so we know. My source is a wikipedia link which I will post below.
Fresno is #35 by population, and rates are 565/3841 per 100,000. Sacramento is #36, and rates are 676/2937. Slightly worse on violent crimes, significantly better on property crime and the mayor is a Dem. I don’t know where your “80” came from, can you explain what you are comparing here?
Dallas is #9 by population, and rates are 775/3185. The mayor was a Dem when elected, but has since switched parties - and cannot run again. Nevertheless, it compares slightly worse on violent crime and far better than Fresno - a much smaller city - in property crime.
Fort Worth is #17, and rates are 560/3215. Fairly comparable to Dallas.
Tulsa is #47. and rates are 1041/5456. They have a serious crime problem. Again, where did your “9” come from?
Anchorage Alaska is #66, and rates are 1203/5413. Pretty bad crime rates. As I have discussed, most cities are Dem affiliated. Not sure what else you can conclude from "only 1 is Republican" when you take that into consideration.
Again, most cities are Dem affiliated, os teh data skews that way. I don't see how you can conclude anything from that.
I think you can see that your conclusion is pretty flawed. This is a lie that has been told to help solidify partisan division. Please note that I not saying that Dem run cities are better - far be it. I just believe that all cities have problems, and that the attack of “Dem Run cites BAD” is just a baseless and fact-free partisan attack. It is a lie that works only because most cities are Dem run - which should be the larger concern of Republicans everywhere.
