For instance, in Northern Ireland it was generally thought that:
UUP transfer to DUP
DUP transfer to UUP
SDLP transfer to SF
SF transfer to SDLP
All transfer to everyone else
A little more complicated than that, esp. UUP and SDLP voters who could transfer to the Alliance (i.e. the centre) rather than to their more extreme sides. But anywy...
and so would like to know if a similar scheme is in play in Ireland
Given that the parties aren't as ideologically simple as in NI, transfers are more complex and are also strongly affected by geography - one would note that transfers across county boundaries are often less than fortcoming even between candidates of the same party.
However in very broad generalities:
FF - go everywhere
FG - Lab; Green; PD
Lab - everywhere (exc. PD). SF, Green and FG probably benefit most
Green - Lab, SF...
SF - Lab, Green, FF, other far left...
PD - FF, FG
Socialist - Lab, SF...
You seem to be very interested in numbers and stats, so I'd advise you to check out
electionsireland.com. Here is a link to their main page for the
2002 General. From there you can get the results for all the constituencies, within which you can see details of
complete counts and
transfer breakdowns by constituency, and
changes since the previous election. (The links all go to my own constituency, Cavan-Monaghan, just to provide an example.)
