Given that the Liberal Democrat party is an advocate of proportional representation for elections (Single Transferable Vote being the preferred type - I understand), why aren't polls on Lib Dem Voice conducted using a PR system?
Thoughts?

You can't really do a poll on a PR basis and in any case they pretty much already do that (e.g. 35% say X, 15% say Y, 10% say Z and 40% say U).
What they should be doing is polling using preferential voting, i.e. AV or Borda Count. The latter is easier to calculate.
aye, thats what I meant James, STV is preferential correct?
It's preferential, but it's other feature is that it uses multi-member constituencies, which means that it is broadly proportional (obviously the more members in each constituency, the more proportional it becomes).
STV is both preferential and proportional.
In an election you can't have a proportion of one choice (so you couldn't have 42% of Boris, 36% of Ken and 10% of Brian as Mayor of London). In a poll, you can simply say 42% thought this, 36% thought that and 10% thought something else.
The current (and previous) polls could easily be done along preferential lines, 42% might think something but what if the 36% goes up to 70% with second preferences taken into account?
Just a thought, might lead to some interesting results if as James suggested AV is used
