St. Petersburg, Fla. -- As Republican candidates for President debate for the 13th time, Florida voters face lots of questions. Three civic groups filed suit Thursday against the state's new voting laws in federal court.

The lawsuit follows a week of protests over the tough restrictions making it more difficult for thousands of Floridians to register to vote and cast their ballots. Protestors marched outside the Hillsborough County Supervisor of Elections Office to get lawmakers' attention.

The President of Hillsborough County's NAACP says the voting laws affect everyone -- regardless of race.

"They are trying to keep voters and people from having the right to vote. They're trying to control, apparently, the process of the election in this country," Dr. Carolyn Collins told 10 News.

The League of Women Voters, Rock the Vote, and the Florida Public Interest Research Group Education Fund filed the suit, which alleges "the [voting] law... was enacted with the express purpose of making it difficult for citizens to exercise their right to vote."

Even the U.S. Attorney General Eric Holder may file suit against Florida. During a speech in Texas this week on voters' rights, Holder said, "We're also examining a number of changes that Florida has made to its electoral process. The reality is that - in jurisdictions across the country - both overt and subtle forms of discrimination remain all too common."

A Congressional committee has already scheduled a hearing to investigate Florida's new laws in late January. The Congressional hearing will happen in Tampa, just days before Florida's primary.
