Actually, I think they are doing a smart thing by keeping
quiet.
With so many screw ups every day by the people at the top, there
is no need for any of the opposition parties to say anything.
Everybody can see the amount of big mistakes piling up by the
day.
From the MS escape, minibond saga, IR, hikes in electricity, TC
losses and the insensitive comments by the people at the top in
regards to all these matters, who really needs the opposition to
remind ad nauseam. 
They are just letting the despots destroy the
country and waiting for Singapore to implode and then step in...
right, smart but...
