@grindstone cowboy; Abbott didn't drive down that 'Road to Ruin' all by himself, Credlin was by his side as his COS and played no small part in the damage the Coalition inflicted on Australia from September 2013 to September 2016.
Expecting Credlin to offer up viable alternatives to what's confronting Sydney is a lot more than one bridge too far! She'd have to see the Light, have Morrison's God speak to her and undergo a miracle.
