Charlotte voters will head to the polls tomorrow to cast primary ballots for city council races, but there probably won't be too many of them. This an odd-numbered year with only city offices on the ballot, so Mecklenburg County Elections Director Michael Dickerson isn't expecting crowds. "We generally get anywhere from a 4-10 percent turnout for the eligible voters for this primary," says Dickerson. Only Charlotte City Council seats are on the ballot. School board is non-partisan and so are all the town councils, commissions and mayors races, so no primaries for those races. "Invariably, I'll always get a call from two or three people from Huntersville, complaining that their precincts aren't open next Tuesday," says Dickerson. Voters will narrow down the five Democratic candidates for city council at-large to four. They'll face the four Republicans in November. The primary will decide the winners for District 2 in northwest Charlotte and District 7 in south Charlotte. The District 7 race is the only Republican primary on this year's ballot. Democratic primaries are also happening for District 3 which covers west and south Charlotte and district five which covers most of the city's east side.
