I'm sorry, but WTF? What the hell did Obama have to do with that ruling, other than serving as a convenient scapegoat in your story? It was a Supreme Court ruling, and last I checked there was still a separation of powers between the Judicial and Executive. Obama publicly called it a devastating outcome.
Obama appointed 1 of the 4 Democrats who voted in the minority, his only appointee up to that point https://en.wikipedia.org/wiki/Barack_Obama_Supreme_Court_can...
So he literally did all he could, subject to the constitution, to prevent this ruling. The logic of mentioning Citizen's United here is like people complaining that abortion rights were taken away during Biden's term. In other words, there is no logic other than a crude misdirect.
Not to say that actually happened. Just pointing it out.
