Some voters may find themselves voting at a new precinct come the March 6 Presidential Primary with re-districting expected to have a slight effect on where Warren countians vote.“Warren County had about a four-percent growth according to the census so it will not cause a great deal of change, but by law, it will necessitate some changes,” said Election Administrator Donna Yates during her address of McMinnville Noon Exchange this week. “We are required to keep districts equal, within 10 percent of one another for representation purposes, so things change somewhat after each census.”Re-districting will be conducted later this year as it is decided how to draw up the districts so they all have close to the same populations within them. However, Yates said the marginal growth means there will likely be no major lines re-drawn.“You have people who live in contiguous districts some of which may be moved to the district closest to them,” Yates said, noting there are 17,815 registered voters in Warren County.
