It's a dangerous precedent to set and even to talk about. Dems discussed putting Bush in prison over what he did and ultimately decided not to. And you don't want the standard to become that every person will be put in prison after their service because the next time it won't be you.
There are a couple that I'd like to see pulled in and questioned a little more throughly, but we can also be a little magnanimous.
In my opinion, your attempt at equivalency falls way short. Bush may have done things that his detractors disliked, but in no way did he do anything that even hints at the level of corruption that has been exposed by Democrats during this election cycle. The RICO-like activity of the Clinton Foundation, the clear mishandling of classified materials, lying to congress, obstruction of justice, etc, etc, etc....that has been exposed cannot, and should not go unpunished. Special prosecutors need to be put in place and guilty parties, whomever they may be, need to be held accountable. I'd prefer hanging on the National Mall, but would settle for any sentence as long as these elitist fools are held accountable. To do nothing, and let them off without any punishment only propagates the cesspool, and the anger it creates among the electorate.
