For some years, the National Conference of State Legislatures has been keeping a very useful database of bills in state legislatures that amend election laws. Here is a link to that database. One can choose to look at all the election law bills introduced in any single state, in any recent year. Or one can choose to see bills in all states on particular election law subjects, or any combination.
The hard work of finding these bills is mostly handled by Jennie Drage Bowser, with help from Tom Intorcio and Tim Storey, all members of the staff of NCSL. The headquarters of NCSL is in Denver.
The database does not include pre-filed bills. Bills don’t appear on the database until any particular state legislature has convened. Almost all state legislatures will meet in regular session during 2010. Most of them convene the second week of January.
