9 votes, maybe 12, separate Cherfilus-McCormick and Holness in congressional race. Why so close? What happens now?

The leading Broward-based candidates, Holness, Thurston and County Commissioner Barbara Sharief all held elected office years. And in Broward, Smith said, people voted for candidates they knew. Holness finished first in the county with 29.4% in unofficial results and Cherfilus-McCormick was second, with 21.5%.
