I too agree that TCB's votes would be less than 50%, closer to 45 % but TT would have got only 35 to 40 % with TKL, no matter how non-electable he is, winning back his deposit. The reason why I differ from you regarding TCB's supporters is that they are different from the usual PAP supporters. Just go to his website and see the adulation they have for him. They talk as if the ruling party is really the other side even though his strongest supporters are ex-PAP. The rest are the middle ground opposition supporters. Even today, his Facebook is filled with well-wishers and people following his every move, giving him encouragement. The other reason is that TJS and TT supporters are at extreme poles of the spectrum. Except for a few who were wrong in understanding where the candidates stood, no one would switch from one to the other. And precisely because of this largely leftist hardcore character of TJS's supporters, many would not have gone for TCB because he held the middle ground and because some would have viewed him as the second PAP candidate. These voters would possibly simply spoil their votes or go for TKL to deny TT. So only the moderate half would have plumped for TCB having a difficult choice deciding between him and TKL just to deny TT. But I strongly believe TCB has only a PE interest because of his past ties with the ruling party unless there is a breakout from the PAP, he will not join any of the existing opposition parties.
