CO comes from incomplete combustion and you’d usually only have detectors for it around gas heaters, generators, stuff like that. Maybe you meant carbon dioxide (CO2). I don’t remember ever seeing one around a voting booth. I’d consider them a good idea though, not because CO2 poisoning is a serious concern per se, but because high CO2 means that you’re breathing air that other people exhaled, increasing your exposure to airborne pathogens.
CO2 is a non-issue in open places with people around. The one gas our bodies detects well is CO2. If there’s even a tiny percentage higher than background, people are going to quickly notice.
