The left doesn't say that one man doesn't have the power to pull strings, the left says that there's no evidence of Soros doing it.
A subtle distinction, but an important one.
Leonard Leo literally hand-picked every judge that Donald Trump appointed, all 234 of them, including 3 supreme court justices.
Leo then paid for nonsense cases to be filed in jurisdictions with friendly (read his own hand-picked) judges. These cases were all based on lies. Because it never mattered if there was any truth to them. They then get kicked up the chain to Leo's hand-picked supreme court, where the justices rule how Leo wanted from the beginning. Well, 3 hand-picked, and 1 bribed, all that's needed from there is to get Alito to fall in line, and that man has Fox News brain so bad that it's scary.
And that's how one man can shape the law in any way he wants, even if congress and the presidency are controlled by Democrats
