Elections in the United States are administered at both the federal and state levels. Congress determines the timing of congressional elections, which are held every even-numbered year in November. Most election laws and procedures are set at the state level, such as precinct and polling place definitions. The Help America Vote Act of 2002 aimed to modernize elections following issues in 2000, mandating states replace outdated voting machines, improve poll worker training, computerize voter registration, and allow provisional ballots.
