Leo and the rest of fedsoc have been doing this for a while. The article describes some of their successes and how they’re raising the stakes - are you responding to just the headline? What would be the liberal analog here anyway, there isn’t a single group with anywhere near the same impact on the judiciary.
And generally speaking the “liberal” cultural values are more popular, so there isn’t really a need for this kind of cultural revanchist strategizing/fund distributing. Which is why you see their projects focused on democratic means rather than the courts.
George Soros Open Society non-profit is the counter to this. It specific finds like minded organizations and political candidates and shovels money at them.
