Is prosecutorial politics broken?

[Blair]

There's a huge problem with the prosecutor-politics pipline; and equally politicians are to blame for spending years clipping selective parts to make them look better; the democrats use to do it to look tough & now do it show how reform minded they are (Dough Jones irrc used his work as the US Attorney to turnout the AA base in 2017)

It's most probably just because I come from a different system but the practice of prosecutors having to be elected or then running for office is a huge problem. The best example is Chris Christie who was infamous for using his office as a US Attorney to build his political career; it just leads to lawyers who seem to spend their time in public office getting themselves ready for the next campaign.
