They weren't saying it was unique to the GOP, and your comment almost makes it sound like the two major parties are equivalent in this respect. At a national level, I think their point stands. I find this distinction actually relevant here given the current renewed interest in a higher nationwide standard for voting accessibility and representation. Also, consider that the states with independent redistricting commissions to mitigate or prevent gerrymandering are all historically left-leaning: https://en.wikipedia.org/wiki/Redistricting_commission
