"Florida, for example, has put stringent restrictions on voter registration drives, imposing fines and even criminal penalties for the slightest infraction of complex rules. Groups like the League of Women Voters and Rock the Vote say they won’t participate in such a system. Election officials say the rules limiting these drives are a significant reason that new registrations are lower than they were four years ago.
Since President Obama was elected with help from a surge of support from new voters, similar laws have been passed or introduced in South Carolina, Michigan, Illinois, and several other states as part of a Republican effort to restrict voting by groups that tend to vote Democratic."
