Starwoman, if Abbott was articulate, able to think on his feet, true to his convictions and didn't suffer from foot in mouth he would have nothing to fear doing interviews to any one on any show.
That's the reason Abbott avoids interviews, handling srutiny is part of politic, if you can't the public should rightly question the character and motives.
Pyne was able to apear on Q&A and apart from the winny voice did OK.
Turnbull, well he never has a problem doing interviews and handling scruitny, in fact Turnbull has the capacity to turn a negative into a positive.
