In the US I’d have 2 amendments added to the constitution
First is where for a voting precinct the average amount of time for people in that precinct to vote is 35 minutes or less. 8 hour voting times should be unconstitutional.
Second is where all districts, regions, and precinct should be drawn by a mathematical formula. No gerrymandering allowed. It should be simple squares or rectangles. No favoritism in any way shape or form. It shouldn’t consider party affiliation, race, creed or anything. Just simple squares and rectangles.
If there is favoritism in one way it can be screwed with by people to create favoritism another way.
