Politics doesn't directly kill people earlier (usually), but policy can either tamp down or exacerbate other problems.

Utah and Oregon both have large urban prosperous populations who can afford healthcare and these areas are known for outdoor healthy lifestyles. SLC is loaded with fitness oriented businesses. They are socioeconomically very similar.

In contrast, many of the worst outcomes are in places that are poor, have major drug or violence epidemics, and also have little in the way of public support for healthcare.

Bad policy can make a bad situation worse more than good policy can improve an already pretty good situation.
