As I’ve always understood it, it’s the job of the Sheriff’s department to “protect and serve” with a county-wide jurisdiction rather (as opposed to, e.g., city police or state troopers). In other words, I’ve always just thought of them as County Cops (a signficiant thing, if you live in a large Texas county that is all county with two or three “dots” called towns).
That said… Why do we vote for Sheriff? We don’t vote for Chief of Police (hired by the city council) or head of the DPS (presumably appointed by the Gov.). And why does the Sheriff have a political affilication? If their job is to enforce laws, serve warrants, etc., why should it matter if the Sheriff is a democrat, republican, or something else? Is this just a Texas thing or do all state’s counties (or parishes or whatevers) have elected, politicized sheriffs?
