I've just launched Irish Election Stats, a site you may be interested in. It brings together various data sources into a single statistical model to forecast seats for the election.
First time I've attempted something like this, but very pleased with the output so far. As new polls emerge, the forecasts will change.
I'm a huge fan of Nate Silver and his work on US elections. I've done my best to adapt his approach to the Irish system. We'll know on the 27th whether it's worked or not.
