in Dark Money as he continues his quest to form the U.S. Judiciary to his liking. btw, here's another article that goes into greater detail regarding the secretive donor of that $1.6B...
When it comes to SCOTUS nominees, I can't imagine all of it going to judges like Barrett, Kavanaugh, Gorsuch and Alito...after Mr. Leo takes his cut (illegally?), I'm guessing that it goes to the individuals who really matter....i.e. the Senators who must confirm those judges...they can then use those funds for reelection campaigns, etc. This is NOT what the Founding Fathers ever intended.
While Democratic donors can also use such avenues in defense, they are the one party that has consistently fought to overturn "Citizens United" that opened the floodgates to Dark Money...note President Obama's very public rebuke of the SCOTUS justices over this issue in his State of the Union address...that shows how seriously the Dems want to get rid of such financial abuses.
