I don't think there is a very clear line where money turns into political power. After all, the most influential non-elected people in Washington aren't billionaires or close to it, and if the 2020 election cycle taught us anything, it was that the effect money has on political advantage is hilariously overestimated. How much did Bloomberg sink into his own race, as well as into backing the Florida Democrats, and also into backing McConnell's opponent in Kentucky? In excess of a billion dollars, and all of his backed candidates including himself failed spectacularly in their races.
