The estimated spending on the 2026 election season is $11.6 billion [1]. One primary has had an estimated $60 million spent on it (ie the Michigan Democratic primary). Thomas Massie's primary had an estimated $35 million spent on it. A GOP Super PAC has earmarked $342 million for 8 Senate races [2].
Over $5 billion was spent on lobbying in 2025 [3].
To truly move policy you need to get pliable representatives first and that's not just money. There is a pipeline here. First, you get the right connections. That could be coming from a wealth family, be the nephew or grandson of some politician, do your time as a staffer or whatever. Going up through the ranks acts as a giant filter to make sure you will maintain the status quo. So you have to find candidates to run for these offices who have been weeded out by the existing processes. And if you don't have enough of them, the DNC or RNC will spend selectively against you in the primary and general election. And an increasing number of races have over $100 million spent on them.
Buying back democracy would be very, very expensive.
And then after all that there's the income and jobs pipeline. Your children get six-figure jobs with think tanks and interested companies. You leave office and get placed on boards of large companies. You can't compete with that.
