But those efforts, say campaign officials, have been complicated by laws approved by state legislatures since 2008, including some that place additional requirements on groups that register voters.
It is disheartening to see voting becoming harder in states across the country, said Katie Hogan, a spokeswoman for the Obama campaign. She said the campaign is doing the challenging work of registering voters, even when Republican legislation is trying to make it more difficult.
A dozen state legislatures passed rules last year requiring voters to present state-issued photo IDs when they arrive at the polls, according to the National Conference of State Legislatures, although in four states the laws were vetoed by Democratic governors.
Florida and Ohio will cut nearly in half the number of days for early voting, and Florida lawmakers reversed rules that had made it easier for former felons to vote.
Florida also passed new rules governing groups that register voters, requiring them to turn in completed voter registration forms within 48 hours or risk fines. Groups previously had 10 days to file the forms. As a result, the League of Women Voters, the Boy Scouts and several other organizations that register voters halted efforts in Florida.
Opponents of the laws say Republican legislatures have attempted to tamp down turnout among minorities, who tend to vote for Democrats.
Were seeing the squeeze put on voters of color. They were hit by the economy, they have to re-register to vote, and now they are hit by new registration requirements, said Judith Browne Dianis, a civil rights lawyer and co-director of the Advancement Project, which is challenging the laws in several states.
