A fight over early voting in Florida deepened on Wednesday as an election official who will oversee voting in the Florida Keys in November’s presidential election refused to reduce the number of early-voting days despite a warning from the state’s governor. Harry Sawyer, the supervisor of elections in Monroe County, which includes the Keys, told Reuters he plans to allow 12 days of voting ahead of the election even though a 2011 Florida law cut the number to eight. Florida is among a handful of states that could determine the outcome of the race between Democratic President Barack Obama and Republican candidate Mitt Romney. The issue of early-voting restrictions has also played out in Ohio, another prized swing state, where the Obama campaign filed a lawsuit to legally challenge moves by state officials to reduce the number of early-voting days. Democrats claim early voting restrictions are designed to limit Democratic voter turnout, particularly among working-class voters, who are more likely to work jobs with less flexibility to take time off to vote. Republicans argue the measures are intended to reduce voter fraud.
