praxidice,

I'm not saying he won't get any votes.

I'm saying that he will take votes away from the Libs and Nats (like Joh did) but I'm also fairly certain that even if they win a few seats, he won't get enough to make any difference at all to an incoming government.

He is going to take quite a few votes of people who can't stand Gillard, & want her gone, but could never vote for the Libs, or Abbott.

At this stage of the leadup to the 2013 federal election the opinion polls are not showing much support for the "Others" category. Neither Katters AP nor Palmer's United Party seem to have much voter support. What appears to be there seems limited to Queensland (not surprisingly. If Katter and Palmer achieve their stated goal of running candidates in all 150 House of Representative seats, they are going to need a lot of money to mount any kind of national campaign. Palmer certainly has the money to do so, but I doubt Katter has millions of dollars at his disposal.
With the rise of new right wing parties, could this so dissipate the Liberal vote that the very confident, some would say arrogant Abbott, may either just fall over the line or fail to do so. I can imagine voters not wedded to either Labor, Liberal or the Greens getting a bit shy of any party that seems to be producing break away parties such as Palmer United Party...and may drift back to Labor...the Greens or to a high profile independent candidate rather than to go with the Coalition.
It would be so ironic after all of Labor's stumbles and errors of judgment it managed to scrape a victory in what is supposed to be an unwinnable election for them.

A little bird tells me to expect a few surprises from the Palmer camp in the very near future.

Yet we still don't know what his party stands for other than a broad motherhood statement along the lines of 'we will unite all Australians'. What does this mean and how will he achieve this wonderous goal?

I can't see Clive Palmer saying no to the mining groups even if it means destruction of agriculural land such as in the CSG fiascos. I can't see Clive Palmer taking a sustainable approach to growth or acknowledging the importance of protecting the environment.
