Its probably something to do with the fact that TDF has already declared him as his successor...............his chosen son. Considering his judgement on every other topic, might one be forgiven for not giving the benefit of the doubt?
Might it also be something to do with the fact that PH seems to support everything TDF does and says and follows him around like his little shadow?
Some might not be reassured by his pedigree.
