Is it possible to reconsider issues?
How can I change my position on an issue?
All of the issues can eventually be repeated (although some choices can make it so you won't get the issue untill you undo them in another issue - like banning elections).
Your decisions on past issues are not recorded. When you make a decision, your nations stats are changed based on that decision and the game forgets what your choice was. When issues start repeating, if you choose the same option the stats will move even farther in the direction that choice pushes them. If you choose a different option, then your stats will change according to that option.
(note: With a new proccess called "issue treeing" the choices on past issues can be directly recorded, but I don't think any issues in the game acctually use this yet)
