Are constituency boundaries the same as last time?
No - new boundaries in line with a 2007 re-drawing.
Just found this quote on that thread:
It should be noted though that these constituency changes might never see an election. Though they will almost certainly pass into law without amendment, as is the norm, the next Census is due out before the next election and due to judgments handed down earlier this year, it's entirely possible that there will have to be a constituency re-draw before another election. Something the politicans will probably deem undesirable. It's been a while since a Dáil hasn't lasted a full term (the last 3 effectively have) and given the size and nature of the current government, there should be the stability there to last a full term, however the prospect of unknown boundary changes close to a general election might be enough to provoke a slightly earlier election than normal.
How things change.
