It is good that WP stated that they cannot form a
government.
If the opposition wins big and life continues to be shit
(because all the PRs are already here or PAP refuses to build more
flats) or PAP deliberately let the economy go to shit, PAP will
gladly lay the blame at the opposition's door. Fortunately PAP will
still be in charge. At most, LKY can say he was distracted trying
to "fix the opposition" but nobody is going to believe him.
