Anything that divides the right is good.

What good does dividing the opposition do in Australia?
If a third party becomes strong enough, you can tip the balance. DLP preferences played a crucial role in the Coalition dynasty's success from '58 on and of course the Joh for Canberra train wreck ended Howard's chances in '87. Not that Palmer's remotely comparable to those 2.
The thing about the DLP was that it directed its preferences toward the Liberals and not Labor; it wasn't a case of a divided opposition so much as a large part of the opposition switching sides.
