Dave while I see the possibility Turnbull and palmer discussing possible blocking of key budget measure, in regards to a forced election I don't see it that way.
With a forced election and polls as they are the lib's would dump Abbott to improve there chances of winning.
Turnbull would be the obvious replacement and guarantee a win, anyone else would be a risk.
The idea of lib's allowing labor to be re elected and then getting Turnbull to lead and win at a latter election makes little sense
