Rudd has his followers. Turnbull has his too. Both are centralists. They would get Labour voters that are anti-Gillard and pro Rudd, possibly almost half of the Labour voters are pro Rudd, would vote there. Half the Liberals are<according to ASF posters are soft Libs so they are for Turnbull. Then there are those that dont want to vote Labor and wont vote Liberal. Add those that are swinging greenies, voted there as a protest, dont like Abbott or Labor. Add all these together and I come up with a sum of around 50% would vote for them. Then for preferences. Labourwould preference Libs last and Libs would preference Labor last.
End result a Rudd- Turnbull government. One problem, who would get to be PM.
Back to the stocks, more productive.
