Liberals closing or widening the gap?

Nanos has the Tories up by five percent, while Harris has the Tories up by 16 per cent.
Nanos has the Liberals closing the gap, while Harris has the Tories increasing their lead.
I agree with what Warren Kinsella says:

I and many other hacks – red, blue and orange – believe CP and MotherCorp are going to be embarrassed, come Election Day, by the Harris-Decima numbers they’re trumpeting day in and day out. The gap is not that huge; there is no bloody way the Tories have that kind of a lead.
