>Our finding is in line with existing results in the literature regarding the US House elections that incumbent candidates gain less from spending, compared to their contender counterparts. This is due to diminishing returns that occur at a certain point, after which incumbent candidates can increase the winning probability only marginally (Green & Krasno, 1988). However, this finding is in contrast with other studies considering electoral systems in Brazil, Japan, or India, where spending effectiveness is equally applicable for both incumbents and contenders (Johnson, 2013; Lee, 2020; Samuels, 2001).
So yea, sorry for providing two scholarly journal articles from two different political eras that support my thesis.
I didn’t realize that this was a bad faith discussion. Now I know.
These studies fail to consider the nature of US politics the last 30 years or so. We had a breakneck election tie broken by the Supreme court in 2000 for some reason. We've had 2 out of 3 times in the hist of the US where the electoral college defied the popular vote.
You don't need to win most states in the US, nor most people. Just target 5-6 swing states and throw billions into the most wishy-washy voters in the country.
It's not enough to only look at elections. The topics that the media discusses, and therefore the options that people are aware of and the issues people base their vote on are decided by mostly privately owned and increasingly consolidated media companies. Nobody will know about candidates that are not approved by some part of the elite in this media landscape. Any opinions that go against the interests of the media owning elite will not see much coverage. Sure, maybe money during elections does not matter that much, but elections are the very last step of the process of picking leaders, and the preceding steps matter as well.
Also, if money did not matter during elections, I doubt we'd see so much spending on them. Studies are being funded by companies and the wealthy as well, so a study or two saying money doesn't matter is not definitive proof.
