You'll approach people with your cheeriest smile and ask if they want to register. Many will be very happy to see you, and almost never will you get a rude response.
Many others will already be registered, but some will just say, "No, I don't want to register and I don't want to vote." You won't be discouraged, and many you'll just let walk on by, but sometimes you'll have a chance to say more.
People give various reasons for not registering and voting. We can’t convince everyone, but here are some common reasons they might give, and some possibly helpful responses.
A. “Voting doesn’t make a difference”
B. “I might be on a jury”
D. “Voting here is rigged”
It's true that our state is gerrymandered, but see recent court cases re fraud showing that the vast majority of votes are counted accurately and honestly. Votes in SC are audited regularly.
E. “I have disabilities that make voting hard and I don’t trust voting by mail.
Many court cases have shown that voting by mail is honest and effective, but if people want to vote only in person, there's curbside voting at every poll so they can vote in their car if needed. Also, electronic assistance is available with those who have communication issues (with hearing, seeing, or literacy), and all voters with disabilities can request assistance from anyone but candidates for office.
F. “Voting machines can be hacked”
