The Rev Willie McCrea treads carefully in Coalisland. The sectarian geography is subtle in Mid-Ulster and he is anxious not to knock a nationalist door by mistake.
"It could lead to a confrontation and I don't want a row," says the DUP man. Political divisions run deep here. There is no middle ground in Mid-Ulster.
The Alliance Party receives just 1 per cent of the vote. Sinn Fein is the largest party. It won 40 per cent support in last year's Westminster election when Martin McGuinness unseated Mr McCrea. Until then, Sinn Fein and the SDLP had been neck and neck in the constituency, but Mr McGuinness outpolled the SDLP candidate, Denis Haughey, by almost two to one. Mr Haughey is running again along with his party colleague, Patsy McGlone.
The Ulster Unionists gave Mr McCrea a clear run last year, but normally the unionist vote is evenly split between the UUP and the DUP.
Both parties should secure a seat each in tomorrow's election. The SDLP is sure of one and Sinn Fein of two seats.
The battle will be for the sixth seat. The SDLP says it can recapture lost ground. Sinn Fein says it will hold its Westminster vote and have all its three candidates elected.
They are Mr McGuinness, Councillor Francie Molloy and the former IRA man involved in the 1970 arms trial, John Kelly.
Unionists and the SDLP claim Sinn Fein will be punished at the polls for its poor constituency work.
"Lazy is one thing we aren't," says the party's local publicity director, Paul Henry. Premises acquired to set up new party offices in Coalisland and Magherafelt are evidence of Sinn Fein's commitment to the community, he says.
The SDLP's Patsy McGlone says: "The new atmosphere of reconciliation and compromise will suit the SDLP. Both Denis Haughey and myself should be elected."
But if Mr McGlone is wrong and the SDLP secures one seat, who will get it? Mr Haughey (53) was a senior talks negotiator. But Mr McGlone (38) has a high local profile.
Also worth watching will be how the two UUP runners fare. The party will win one seat. Its candidates are anti-Agreement John Junkin and pro-Agreement Billy Armstrong.
