The financing of electoral campaigns in the United States happens at the federal, state, and local levels by contributions from individuals, corporations, political action committees, and sometimes the government. Campaign spending has risen steadily at least since 1990. For example, a candidate who won an election to the U.S. House of Representatives in 1990 spent on average $407,600 while the winner in 2022 spent on average $2.79 million ; in the Senate, average spending for winning candidates went from $3.87 million to $26.53 million.
