This is really interesting, did not know this. In 1976 and in 1980, when Jimmy Carter ran against Gerald Ford, and Ronald Reagan, respectively, for President, the presidential campaigns raised… 0 dollars. That is, both Carter, and Ford and Reagan, took no campaign contributions. Instead, all the campaigns were paid for only by public financing through the $1 or $2 check-off box on annual tax returns. Amazing. The next elections will raise money in the billions. Not hard to figure out which system is better for the future.
It is good to learn from history.
