That response doesn't make any sense. Why can't you guys just use empirical evidence to identify a problem and propose a solution that you think will solve that problem? From there it should be easy to justify how it is okay to enact a law that will prevent some legal people from voting.
Why? Because their thinking & conclusions are faith based.
They believe that the reason they don't win more often is because of illegal voting, despite having no evidence to back up that claim.
They believe it's easy for anybody to get ID when that's not necessarily true at all. They don't realize that birth certs aren't free, nor are marriage & divorce records dating back decades. They don't realize that lapsed ID often means a person has to start over from scratch.
They believe it's not possible for people to function w/o valid ID, even though it obviously happens all the time.
Most of all, however, they believe what this guy says to be true, and are willing to endorse any behavior that enhances their team's position-

It's the new Jim Crow, accomplishing the same ends via different means, that's all, means with a little thicker veneer of respectability. It's not overtly racist, but that's just one component of disenfranchisement attempts aimed at voter blocks who aren't them.
