Yes I think they should be able to vote and the reason why is because The drive to lower the voting age from 21 to 18 grew across the country during the 1960s, driven in part by the military draft held during the Vietnam War. A common slogan of proponents of lowering the voting age was "old enough to fight, old enough to vote". Basically I think people should be able to say who they want to vote for. Hope this helps!
