If lowering the murder rate in your city is your primary goal, you might want to consider not electing a Democrat.

I saw something on Facebook the other day that sparked me to do some independent research. This is what I found:

Out of the 10 American cities with the highest per capita murder rate, 9 of them have mayors who are Democrats. Not only that, but all nine of them have had Democrat mayors for long periods of time. On average, for about the last 30-40 years. The shortest amount of time is about 16 years.

The other city is Las Vegas, which has had an independent mayor since 2011. However, before the current independent mayor, they had exclusively Democrat mayors going back to the early 1970’s.

Let me be the first to point out that correlation is not causation. I’m not saying that having a Democrat mayor causes a high murder rate. I’m not saying it doesn’t, either.

But there’s certainly a lot of proverbial smoke there. So here are some possible explanations:

1. There’s no causality involved at all. Possible, I suppose, but there’s still a lot of smoke that needs to be explained.

2. Cities with higher murder rates simply tend to vote Democratic. Worth considering. But then, that begs the question about why that would be true.

3. Republican mayors implemented policies that led to higher murder rates, and the Democrats are still cleaning up the mess. This doesn’t seem plausible to me. Given the length of time the Democrats have been in office, one would think that there would be some significant progress in lowering the murder rate by now.

4. The Democrat mayors implemented policies that led to higher murder rates. This isn’t to say that they intended to do so. Just that the policies have some unidentified side effect that results in higher murder rates.

There are probably other explanations.

But one thing seems crystal clear to me: Whatever good Democrat policies do for cities, they do not lower murder rates.
