Having to host at least three elections and for the first time open doors to weekend voting, Bulloch County’s poll workers and locations are in for a busy 2012. Monday, the Bulloch County Board of Elections and Registration gathered in the county courthouse to confront the challenging schedule in its first meeting of the election-heavy year. The group reviewed a calendar that marks dates for two primary elections leading up to a November general election, makes room for a pair of potential run-offs in August and December, and reserves three dates — one for each election — for voters to cast ballots on upcoming Saturdays.
