 Tsang apparently won public support because of his strength in the details of policy issues, while Leong's understanding of public finances and other policies seemed to be weaker than Tsang.Both candidates gained increased support from the general public after debate as indicated by the survey results, compared to a previous survey where only 65.3% and 16.1% of the respondents support Tsang and Leong being elected respectively.Nevertheless, all the figures reflect an unexpected performance displayed by Leong, who adopted a combative approach and seized every opportunity to attack Tsang's record, especially in terms of environmental protection and the possibility of universal suffrage by 2012.
