The Democrats have been buoyed by internal polls that show they could gain an extra geographical constituency seat as a result of the scandal surrounding Gary Cheng. Polls conducted in New Territories East and West after the scandal found the Democratic Alliance for the Betterment of Hong Kong's vote had dropped in both constituencies. The Democrats interviewed about 2,000 people in each constituency. The poll found the share of votes for the DAB in New Territories West had gone down from 24 per cent to 22. Even such a small change could be crucial to its chances of securing a second seat. Five of the six seats are expected to go to Democrats Lee Wing-tat and Albert Ho Chun-yan, the DAB's Tam Yiu-chung and unionists Lee Cheuk-yan and Leung Yiu-chung. The sixth seat is a race between Democrat Albert Chan Wai-yip and Tang Siu-tong, running mate of Mr Tam. The poll showed Mr Chan about three per cent ahead of Mr Tang. However, Mr Chan said the seat was not yet secure. 'Mr Tang has hidden votes that will not be exposed in polls. My situation is still dangerous,' he said. In New Territories East, the DAB share also dropped - from 15 to 12 per cent - after the scandal, although the seat of Lau Kong-wah, who heads the DAB ticket, is still safe. Wong Sing-chi, who is on a second Democrat ticket but lagging behind Andrew Cheng Kar-foo, planned to highlight the DAB's difficulties. 'They can keep their vote share because many voters still do not know they are DAB members. I will appeal to their consciousness,' he said, targeting Mr Lau, who switched from the pro-democracy camp to the DAB. Mr Wong is fighting for what is probably the only undetermined seat in the constituency, against Richard Tsoi Yiu-cheong of The Frontier. A recent poll found Mr Tsoi led Mr Wong by more than five percentage points.
