I don’t know about compulsory, but would be nice to vote FOR someone.
For most of my adult life, too much of my voting has been holding my nose and voting for who I dislike the least!
Voting should be a rewarding, joyous occasion, with a legitimate hope for improvement. Most of the time I see it as a blocking exercise - “well if enough of us turnout, maybe we can keep the bigger jackass out of office.”
Or at least a “None of the Above” option, which, if it got the most votes, meant a new election with the candidates from the previous ballot banned from running.
