Taylor's natural ground is economics, so that could give him a good start although, it should be noted, he had trouble as shadow treasurer performing against Jim Chalmers last term.
If the conservatives decide not to move quickly against Ley, that buys her extra time, but it is doubtful she would be able to put it to long-term use. Apart from the pressure from the polls, the Taylor forces and the media would ensure she was always living on borrowed time.
But the nature of Ley is that even under the worst of political circumstances she holds her nerve, trying to keep the wolves at bay, one day after another.
The "wolves" of course are not just in the Liberal ranks. Ley is also trying to deal with the Nationals, who shattered the Coalition last week. She would like to put the team together again, without giving ground over the issue of shadow cabinet solidarity that triggered the breach.
On Friday she allocated to Liberal shadow ministers the portfolio responsibilities given up by the Nationals when they split.
