You are looking at only part of the data and only at the part that supports your story. Donations are not all public, only donations from “little people” are public. The wealthy use Super PACS. From the Washington Post:

Meet the wealthy donors pouring millions into the 2018 elections By Anu Narayanswamy, Chris Alcantara and Michelle Ye Hee Lee Updated Oct. 26, 2018 Wealthy donors who have given at least $1 million contributed 74 percent of the $1.1 billion that has flowed this election cycle into super PACs, which can accept unlimited contributions from individuals and corporations.

While these groups cannot coordinate their advertising with candidates or political parties, they often work closely with official campaigns, and they are influential forces in this year’s congressional midterm elections.
