The constituency has added a seat since 2011, but has also taken in a chunk of Dublin South.
The addition of these mainly more affluent areas is likely to help Fianna Fáil candidate John Lahart.
Anti-Austerity Alliance/People Before Profit member Paul Murphy is very strong in the area and he will be hoping to bring in second candidate, Sandra Fay.
Both candidates have divided up the consistency, with Mr Murphy taking everything east of the Old Bawn Rd, and Ms Fay asking for first choice in the area to the west.
However, Sinn Féin’s Sean Crowe will also be battling to bring in running mate Sarah Holland.
Labour won two out of what was formerly a four-seater last time around, but the question now is whether they will be even left with one after Friday’s vote.
Eamon Moloney won a seat for Labour in the last general election; however, he resigned from the party last year after disagreeing with a two-candidate strategy that Labour had proposed for Dublin South-West.
He is now running as an Independent but will have a massive battle on his hands to retain his Dáil seat.
Pat Rabbitte also took a seat for Labour in 2011, but he has decided not to run for another term. The party have selected Pamela Kearns as their candidate.
Fine Gael have put forward three candidates — Colm Brophy, Anne-Marie Dermody, and Karen Warren.
It is expected there will be at least one Fine Gael seat in the constituency and while the bookies favoured appeared to be Mr Brophy, Ms Dermody has a high profile on the ground and is running a strong campaign.
Senator Katherine Zappone, who is running as an Independent, will put up good fight, as will Renua’s Ronan McMahon.
Water charges is an important issue in this constituency.
Jobstown was at the centre of one of the nastiest anti-water protests which saw Tánaiste Joan Burton locked into her car for at least two hours as she tried to leave an event.
In the working-class areas, such as much of Tallaght, crime, housing, as well as jobs are high on the agenda, while childcare and housing is important for the vast majority of constituents.
