The table included in the article does seem to indicate that bankers are not her top contributors, but I was unable to discern how that data was tabulated. The footnote on it simply says the sources are the Federal Election Committee and Vox, with links to only the landing pages on those sites. I spent a few minutes trying to get meaningful data from the FEC site but failed. Either I'm not very good at navigating it or the creation of the table in the article took considerable time and effort.

I would love to know exactly how the data in that table was selected, because the very easy to read table at OpenSecrets.org shows 4 of her top 6 lifetime contributors being from the banking industry (Citigroup, Goldman Sachs, JPMorgan Chase, and Morgan Stanley) with the other 2 being a law firm (DLA Piper) and a PAC that explicitly exists to try to put a woman in the White House (Emily's List).

Given that the whole point of this article is to disprove the generally accepted narrative that Hillary Clinton has received a huge amount of Wall Street money, the references to back up that claim are somewhat lacking IMO. If the author wants me to believe Ms. Clinton is not beholden to the banking industry he could start by explaining what's wrong with the numbers provided by OpenSecrets.
