This is a problem of Stated preference vs. Revealed preference. You ask them what they think and they'd tell you "that's awful, I can't believe that, that's so unfair" but you put them up on the ballot at the midterms and get them to repeal it and all of a sudden it's about being "tough on crime" and "keeping our streets clean".

Also, prisons are often located in depressed small town as a stable source of government jobs. Those people don’t want to go back to being in a depressed economy.

The most extreme example of this is that the site of the 1970 Lake Placid Winter Olympics was designed to be used post games as a prison, which it is today.

Not really, you are assuming the people vote on a lot of decisions, which is not true. This is a problem related to permanence of executive power. The "cardinal Richelieu" problem (You know that while the government changes, he is above the government and stays. Most of the executive does not change at all when power changes hands at the legislative level).

Ever notice that executive power is the same everywhere? They think the laws are unfair to them, because they have to implement totally unrealistic laws, and get blamed harshly for "small" problems (you know, "harshly" except it doesn't carry any consequences for them, except, at best loss of face).

They respond by not following laws, refusing even to implement judicial directives and the like. Their own (sometimes personal) interest, for them, trumps laws and the directives of judges. They have largely made sure their names are never revealed to the people they serve, as they no longer have the support of the people, and they feel they cannot be replaced.
