Corrupt practices are unethical techniques used by politicians to gain a political advantage in an election. The term is most commonly used in referring to federal and state legislation, called corrupt practices acts, that govern campaigns and elections. These laws prohibit such activities as bribery, ballot-box stuffing, tampering with voting machines, and threatening or impersonating voters. Many of these laws also govern party campaign finances. For example, many states have laws that limit the amount spent by candidates and parties in state and local elections.
Congress established the Federal Election Commission in 1974 following campaign finance irregularities in the 1972 presidential election. The commission enforces federal laws regulating contributions and spending for presidential and congressional campaigns.
