What you see as weakness I see as strength. The right needs to have sound reasons and political power to make right wing rulings. The left only needs political power. What does it matter if the best judges the left can muster are empty talking heads barely better than pundits if they have 5 or more left wing judges on SCOTUS? That they don’t see a need to build a method is liberation. Left wing judges can just write whatever the hell they want to justify their rulings; right wing judges are still bound by sound reasoning, a constraint on their actions. This is one of the reasons the left became culturally dominant: they beat the right in realizing that power is all that matters
