Going after these individuals will invite years of maneuvering that will not result in jail time and will not dissuade others in the future.

Congress and President Trump should spend that effort on enacting laws that secure elections on every level and make this type of lawfare impossible. Term limits should be strict and inflexible. 

Destroy their power to ever do this again.  They abused it. Make it illegal to change statutes of limitations beyond four years for any court proceeding that is not a murder.  Federally hamstring any local or state limits on the Second Amendment.  Enact federal laws that limit 2nd Amendment infringement to illegal aliens and children under 18.  (Every other exemption can be politically influenced, so get rid of them)  

Any emergency power granted to the government must be renewed through both houses and the president every 15 days.  After 30 days, the extension must be obtained by a national in person vote and may only last a maximum of 90 days.

Any prosecution of a President, vice president, or former president or vice president in civil or criminal matters must be approved through a vote in both houses and a majority finding of legality of the charges by the SCOTUS.  All state prosecutions and lawsuits of people holding or having held these offices must be transferred to a randomly selected federal court and meet the burden in that court.

Strip the government of powers it abuses.
