Yes, majority, but how much this time? 55%? 60%? 65%?
If they can get more than 66% this time, game over for local
born Singaporeans. 
Saw this breakdown in some other forum before and i think it won't
be too far off
Plp that will vote for PAP
20% - civil servants and plp who work in GLC related companies
like ST etc.
15% - direct family member from the plp above
15% - new citizens
10% - Traditional PAP supporter (can be elites etc)
Total - 60%
Plp that will vote for opp - abt 30%
Swing vote - 10% (most will end up voting for PAP due to
goodie/fear etc.
