In the aftermath of Watergate, Congress passed the Federal Election Campaign Act Amendments of 1974, which put new limits on contributions to campaigns. Four years later, the FEC ruled that donors could donate unlimited money to political parties (but not the candidates themselves) if the party used that money for "party building activities" such as voter registration drives, but not to directly support candidates. Both the Republican and Democratic parties nonetheless used this money to support their candidates, and money donated to parties became known as soft money. In 1992, President George H. W. Bush vetoed a bill passed by the Democratic Congress that would have, among other things, restricted the use of soft money. President Clinton pushed for a similar bill, but was unable to get both houses to agree on one bill.
