Malcolm Turnbull is a disappointing Prime Minister leading a disappointingly shallow and untalented party.
He's almost certainly the best to be leader out of the unimpressive bunch, however. Also, given the ridiculous ease with which tax reform can be made the subject of a scare campaign, he likely stands a 50/50 chance of winning the next election, after which the country would continue to stumble on in a generally less than satisfactory manner.
I don't have any doubt that it is actually Labor that is (on the whole) doing serious and useful policy reform work on tax and other matters that is more in the long term interests of the nation. Sure, Bill Shorten has a charisma deficit, but provided he can resist the temptation to increase spending on new ideas (he has enough on his plate funding current ones), he's likely to do more good for the long term budget deficit than Turnbull.
Labor's instincts on most matters are currently pretty consistent and reasonable, I reckon; the Liberals and Nationals, on the other hand, are all over the shop, being riven as they are with undue influence from objectively long discredited American right wing ideologically motivated policy positions.
So, here's to a new Labor government early next year. I hope.
