【明報專訊】IN the Legislative Council (Legco) by-elections held to fill four vacancies, the pro-democracy camp managed to win only two directly-elected seats. It failed to regain its split-voting veto, and Edward Yiu's defeat in Kowloon West was quite unexpected. The pro-democracy camp has lost for the first time to the pro-establishment camp in a one-to-one contest for a Legco seat. That to democrats is a serious warning. It is necessary for them to draw a lesson from the bitter experience and do a thoroughgoing review. It is clear from the by-election outcome that voter mindsets have changed and "political cards" no longer do the trick.
