According to the U.S. Federal Election Commission's website, as of July 10, 2023 the two candidates for U.S. President who have raised the most money are Lee Mercer (D), at $192 million, and John Anthony Castro, at $20 million. The third and fourth highest-fundraising candidates are Donald Trump (R) and Joe Biden (D), respectively.
I think it's safe to say that there is something "weird" going on here, and the FEC web site is not listing true campaign donations according to the straightforward and commonsense meaning of the term.
What exactly do the numbers reported on the FEC website mean? Are these just personal loans to "paper" campaigns or something? If so, is there any verification mechanism that the candidate actually has that much money?
