Give them a narrative about how this actually looks like to a poor person. The average republican judge sees voter ID and thinks about illegal immigrants, but you need to talk about the poor and elderly. Someone who has been poor their whole life doesn't necessarily have a photo ID because they don't have a car. Furthermore, it's really expensive to buy an ID. $100 can be food for a month or two for someone really desperate. If they have to work two jobs, then they don't have the time to even get to the DMV because their hours are really limited.
Paint the narrative instead of speaking only in abstract terms.
That is a pretty good idea and I will probably do it. However, I also mean how can I impact it to their lives? Or their country? If they don't care too much about that poor person, then it won't really do much in terms of getting them to vote on the point.
