This is the latest I can find and it has Irey within ten points, but the margin is getting smaller.

Ten points is still a pretty good gap, and those last few points are hard to come by. Further, this is from a poll commisioned by Irey's campaign. Those are often inaccurate, at least from my experience.
It's good that she's closing, but I'm not sure she can finish it off in four weeks.
