Quite possibly! It sort of makes sense that two 'political animals' like Abbott and Shorten should rise to prominence during the same period though.
And besides, this 'rough time' we're in is bigger than either of them - the 'freakshow' Senate, along with the rise of minor parties and fall of the LibLab primary vote, is a product of voter disenchantment with establishment parties, which has been seen all across the developed world and is unlikely to change soon.
