Your link is completely different argument to the one being made here about "non-voters"
Non-voters are people disgruntled with the current 2 party system, the largest voting block in that group are libertarian leaning people who do not break democrat.
Your link it talking about various voting laws, which largely impact densely populated cities, things like ballot harvesting, out-of-precinct ballot disqualification, and other such rules that have an outside impact on voters in urban cities which are largely democrat.
"things like ballot harvesting, out-of-precinct ballot disqualification, and other such rules that have an outside impact on voters in urban cities which are largely democrat."
What about local elections, most elections are isolated to a particular area? The reason the Republican lawyer made that statement was to show standing. Meaning , why would the Republican party be effected by the various voter restriction laws. They said because it benefits them if voting rights are restricted.
If you are saying that the laws in question reduce the ability of democrats to vote vs republican (as in reduces the numbers more in cities vs rural?) What's the difference? I'm connecting turnout to their success.
Here's a more clear analysis though it is an opinion piece showing that young voter turnout is important for the democrats.
