Presidential races spent $2.4 billion in 2000. By 2020 that number had risen to $6.5 billion.
Not counting the fundraising from candidate-affiliated PACs or joint-fundraising committees, Ballotpedia informs us that through May 2024 Joe Biden raised nearly $190,000,000 and Donald Trump a little over $120,000,000. According to Open Secrets, including the other sources of Biden fundraising, that total comes to $306,014,008. As for Trump, Open Secrets reports that his total comes to $243,952,385. By the time of the fall presidential election these numbers will in all likelihood exceed several billion dollars each.
