泰隆西 is simply Sinn Fein territory. It didn't stop the SDLP's Daniel McCrossan asking the incumbent to step aside and let him give a voice to the area in Westminster, a request Sinn Fein said was "delusional".
Joining Begley, McCrossan and Buchanan on the ballot paper are Alliance candidate Stephen Donnelly, Andy McKane (UUP), the Green Party's Susan Glass and Aontu's James Hope.

Alliance candidate Mr Donnelly, in his mid-20s, took a council seat in May's 弗马纳 and Omagh District Council election - the first for Alliance in almost 20 years.
Ms Glass and Mr Hope cannot be considered as real contenders for the seat, but each of them may absorb some disaffected Sinn Fein or even DUP voters.
Aileen Murphy, assistant editor of the Ulster Herald in Omagh, said that the 泰隆西 seat was always a very safe one for Sinn Fein and that's unlikely to change in this election.
"This time around all three are standing again and the final tally is likely to see them each finishing in the same position.

After enduring four elections in two years and with a fifth on the near horizon, constituents could be forgiven for suffering from severe election fatigue.
"We didn't want to see election posters up on Main Street. It's just not Christmassy. We are sick of politics these last two years. There is so much frustration with brexit, no Stormont and all those issues.
"At a local level the politicians are still active, but at upper levels they are failing us. They are not doing their jobs, but we still have to do our jobs here."
Out on the streets there are those who feel frustrated over the abstentionist stance, just as there are those who support it, and others who have lost all hope in politics.
"What's the point in it all?" said one man. "Nothing will change. It's the same old, same old here and the place is just deteriorating."
