Answer: Some barriers to voting include time slots, where people may wait in line for some time, which is not feasible for some people. Also, another barrier is the lack of mail-in voting for the people who are incapable of going in person due to personal needs or physical constraints (handicaps for example). A solution to all of these issues would be to allow mail-in voting, solving the time constraint issue and the issue of not being able to show up in person.
