That's not how it works. I don't want to see a source I think is credible, I want to see a source you think is credible. The one that convinced you that Sanders received more in PAC donations than Clinton
If you make the claim, it's your responsibility to provide the evidence that supports the claim. This is how it works in every single area of inquiry. Would you claim the Earth is flat, then when asked to see the evidence, would you respond "just Google it, why do I have to spoon feed you everything?"? No, right? Because that's dumb, right? I can Google "flat Earth real" and get millions of pages that support it. You show me where you read the idea that Sanders took more PAC money, let me see your source for myself so I can verify it. Every source I've ever seen says the opposite. They say the opposite because your claim is false.
