With 39 percent of the vote, Roy Moore easily won first place in the first round of Alabama’s special Senate primary. The runoff will be much more challenging, according to new polling.

A new survey by Harper Polling showed Moore leading incumbent GOP Sen. Luther Strange 47 to 45 percent less than a month ahead of the Sept. 26 runoff election. With the combined air and ground support of the National Republican Senate Committee, Strange could easily close that 2 percent gap by Election Day.
