Liberal Party chairman James Tien Pei-chun has set himself a target of winning at least 1,000 votes to take the Peak constituency.
Claiming he knew several hundred of the 3,492 registered voters in the constituency, he admitted he was not sure of enough support for a certain win.
A total of 25.9 per cent of voters, or 997, cast their ballots at the district board polls in September 1994.
Non-affiliated Louis Leung Wing-on, an accountant, won the seat with some 500 votes. Mr Leung is seen as Mr Tien's major rival on November 28.
Mr Tien said his debut in direct elections would prompt more people - both supporters and detractors - to vote.
'People who support me will vote. However, people who dislike me will also come out to vote for my opponents.' He forecast the number of voters would be higher than in the 1994 polls.
