Bridges didn't do himself any favours by the way he responded to the leak of his travel expenses, which in itself was hardly the shock of the century.
His use of ministerial limos to increase his profile around the country, which he's entitled to, shows a sense of entitlement. There are more cost effective ways of getting around but there was no direct cost to the taxpayer who own the limos. It's simply a ledger entry between departments.
But flying in the storm troopers, National's heavy hitters, to stand behind him as he responded to the text was an overkill. It led to the perception that running up expenses is of little consequence to him.
So the storm in the teacup has become a poison chalice for Bridges after the hunt for the leaker was launched and then by week's end canned by Parliament's Speaker Trevor Mallard.
The cops were called in by Bridges, who said the mentally impaired person was receiving the treatment they needed so the inquiry was safe to go ahead. The cops wouldn't tell Bridges the name of the texter who they'd tracked down and he claims he didn't know who it was.
But this was undoubtedly an inside job to undermine his leadership. The texter obviously knew his cellphone number and that of the Speaker and knew the workings of Parliament and the way National's caucus operates.
In cancelling the inquiry Mallard was in no doubt: the texter and the leaker were one and the same person and said they had details of events that anyone outside the National Party wouldn't be privy to.
Still National maintains it's determined to find out who it is. But if that's the case why did Bridges say the process would mean MPs would have to give their consent to their systems being checked which they're unlikely to agree to, so what's the point?
To know the enemy from within but perhaps the truth is too hard to bear.
