In most states voters must register to vote prior to Election Day. Same Day Registration (SDR) allows an elector to register and cast their vote at the same time during an early voting period. Election Day Registration (EDR) allows an elector to register and vote on Election Day. Eight states plus the District of Columbia presently offer EDR. Another two states--California and Connecticut--have enacted same day registration but have not implemented it. Legislation is pending in fourteen states to adopt SDR/ EDR. Colorado has one of the highest registration and turnout rates in the country without SDR/EDR. Implementing these changes does not increase registration or participation noticeably and requires additional costs.
