SDP lost 2 SMCs in 1997, and went downhill ever since then. Ling How Doong and Cheo Chai Chen were not good in managing TC, from what have heard.From the results, it is very difficult to flip a GRC - we saw that both WP and PAP improved on their margins in SK and EC respectively. Now that Punggol and Tampines have become hotly contested GRCs, I expect it to be harder for WP next GE than this. Yes they have 5 years to walk the ground, but PAP also has 5 years to pour in resources to improve their standings.
Before they rejuvenated in 2015 with Paul Tambyah and then subsequently CSJ increased his online presence until this GE, where he bucked the trend of opposition losing vote shares outside of the East.
Depends on how well PSP and SDP conducts their party renewal process then. If they handled it well, they still can divert some resources away from East.
In 2020, PSP nearly won WC GRC. Think PAP shocked also. After that then they gerrymander the entire area.
PSP and SDP need to strategies over next 5 years and continue to push out high-calibre candidates.
PS only 49 years old this year, that is why WP still stable.
