Washington (CNN) - For LaVon Bracy, the pain of racial discrimination, of fighting for her rights as a U.S. citizen, still aches every time she thinks about Florida's new voter identification law.

"When I think I had ancestors that died for this right. I owe it to them ... to do what I'm doing," said Bracy, who years ago helped desegregate her Florida high school and today is fighting to change voting restrictions she feels are designed to keep people like her away from the polls.

Parts of the Florida law - which required a photo ID to vote, restricted voter registration techniques and limited early voting - have been curtailed by federal courts.

Still, it is one of more than two dozen laws across the country approved in at least 15 states since 2011 to deal with concerns around voter fraud and election irregularities. But courts and the Justice Department have reversed or weakened several of those regulations in a flurry of recent litigation.

Anita MonCrief, however, could not disagree more strongly with Bracy.

MonCrief, who is also African American, told women gathered at the Woman's Up Pavilion at the Republican National Convention in August that she resents when other blacks suggest that efforts to crack down on voter fraud are racially motivated.

"This is not the 60's and blacks are not your victims," MonCrief tweeted during the week of the convention. "Do you know any blacks that have been disenfranchised by having poll watchers in place? Neither do I."

CNN senior correspondent Joe Johns will explore the impact of tough new voter laws in an hour-long documentary set to air on Sunday. It focuses on new legislative voting changes in Florida and how those changes may affect the outcome of the 2012 presidential election.
