The poll from Harper Polling puts Moore at 47 percent to Strange’s 45 percent, with 8 percent of voters undecided. The poll also found that more voters consider Strange, who was endorsed by President Trump, as the candidate most supportive of the president by a margin of 10 points.

The data is similar to recent polling figures released by the Senate Leadership Fund, the Senate leadership’s allied super PAC, which found Moore up by just 4 points. But those two surveys are a far cry from others released last week that showed Moore up by a double-digit margin, a discrepancy that underscores how difficult it is to measure a race that’s expected to have low turnout.
