A blue-maga lib relative was going on about how Kamala got all her campaign money from regular people donating but Trump got all his money exclusively from billionaires, tying to make it sound like Kamala's campaign effort was this beautiful grassroots movement of the working class for the poor smol bean democrats.

Does anyone have a good source that does a breakdown of both candidate's campaign funding and realistic estimates on where it came from? Preferably one that I can sort of trust and not like WaPo doing a piece on why it's actually ethnic minorities fault that Trump won.
