How PAP and opposition supporters voted in the Presidential election

Based on the few online surveys, it is possible to estimate (crudely) the Presidential preferences of the PAP and opposition supporters, as shown below.

	PAP voters (60%)	Opp voters (40%)
Tony Tan	35%	0
Cheng Bock	25%	10%
Jee Say	0	25%
Kin Lian	0	5%

*Hardcore PAP voters =  Tony Tan supporters = 35%

      [cf. minimum PAP vote share = 35.2% (Hougang SMC) in GE 2011]

*Middle ground voters = Cheng Bock supporters = 35%


*Hardcore opposition voters = Jee Say and Kin Lian supporters = 30%

      [cf. minimum opposition vote share = 29.4% (Hong Kah North SMC) in GE 2011]






Of course, Tan Jee Say could have won if the following were true:

	PAP voters (60%)	Opp voters (40%)
Tony Tan	30%	0
ChengBock	30%	2%
Jee Say	0	33%
Kin Lian	0	5%
