I disagree with your assertion. Even so, alistairSH's conclusion: "We'd do well as a country to allow nationwide mail-in voting." like it was solution to solving lack of voting from renters, when cherry-picking data gets us 12 points at best. It might be part of a solution, but it's demonstrably not a majority difference.
All this presumes every possible vote is equally valid.
Arkansas had <26% (457,856 votes / 1,762,024 registered voters) [1].
38% is looking pretty good.
