Sure, but the existence of voting booths themselves aren't wrong. You're looking at it as if it is a symbol of super backwards technology, but if that's the case, why can't you simply vote by app in those three states? "I can't believe you still have to vote by mail", etc.?
I mean, for all the ease of being about to smoke a blunt and vote at the same time, only Oregon of those three rank high in voter turnout, and even Oregon's turnout is not as good as these other states that are still using these crazy voting booths. Are those three states even trying, lol
