Every year the Federal Election Commission publishes a very useful free reference book that contains contact information for state election officials. The 2017 “Combined Federal/State Disclosure and Election Directory” is now in print. It can be obtained by phoning the FEC at 800-424-9530. The 147 pages of content are also on the FEC’s web page.
The book also has a section mentioning which legislative committees in each state handle election law bills.
