Sorry for the delayed answer.
I fail to see how using OpenSecrets is a problem. Be it private donors or foreign groups/governements, all the money is (officially) there, is that not so?
Because in the comment you are answering to, the comparisons are done also against groups funded by private donors. Which should also not be registered under the act. And again, those other groups massively outspend the pro-Israel ones.
What other foreign nation lobbying group donates $14M to the opponent of a congressman and pays for attack ads against him to hurt his chances in an upcoming election? It’s unprecedented.
I have honestly no idea? But from my understanding, any other random lobbying group could also do the same, if they had an interest into it. Hell, maybe they do already but there has been no reporting on it because it’s less interesting if it’s the NRA or Lockheed-Martin?
Tbh this is more than mildly infuriating…
