  1. Running for office is a full time job and you will completely neglect the current one (which leads to mistakes and inaction)
  2. There are many conflicts of interest that arise between doing your current job with the current administration and campaigning to replace said administration. That can lead to decisions made for the wrong reason.

Both of these are bad for taxpayers who want to make sure that everyone is working hard and fairly while in whatever office they were elected into.
