You're running out of time if you're not registered to vote in Mississippi and want to take part in the November 6th election. Circuit clerks' offices across the state will register you up until today's deadline of 5 p.m. If you're mailing a registration in, it has to be postmarked by no later than tomorrow. Among a myriad of other items on each county's ballot, voters statewide will decide the outcome of Mississippi's two U.S. Senate races.
