A Workers' Party CEC member, Yaw Shin Leong, bragged in his blog
that he voted for PAP's Teo Ho Pin in the last election. Now we
know why the PAP cannot lose because even opposition members in WP
is voting for them

Last Sunday, during WP's walkabout at Nee Soon East SMC &
Ang Mo Kio GRC. A party member shared with me about rumblings in a
local Internet forum (Sammy Boy) that some forum participants were
unable to reconcile with the fact that I voted for Teo Ho Pin in
GE2006.
This party member subsequently sent me the forum link here.
I am of the view that it is a trait for humans to operate within
the paradigms of subjectivity and objectivity. Personally, I do not
believe in opposition for opposition's sake. In this regard, there
is nothing inherently wrong for me to vote for an MP, regardless of
his/ her partisan background, whom in my opinion is the better man
who can better serve the interests of Singapore and my community
(Bukit Panjang SMC).
Consciously in so doing, I have raised my understanding on a
required 'standard for parliamentary entry'. In another words,
being a forefront partisan activist, myself am of the view that a
particular candidate from the ruling regime deserves my vote rather
than another from the opposition, this invariably reminded me that,
the WP has to 'strive so much harder', 'offer so much more' and
'convince so much more' in order 'to get there'.
Actually during GE06 itself, there were also some in WP who raised
their eye brows when I shared with them that I will be voting for
Teo Ho Pin. On polling day, one urged me that since the incumbent
will win anyway I should perhaps 'spoil my vote' instead. However
as a citizen of our constitutional state, I take my voting duty
very seriously and will never waste my precious vote, unless the
political circumstances really warrant it.
The interesting question perhaps would be, if a WP candidate is to
offer himself/ herself for election in the constituency I reside,
will I vote for this WP candidate? Partisan considerations will
certainly weigh heavily in my considerations. Having said that,
ultimately this WP candidate has to convince me that he/ she has
what it take to better serve the interests of our country and the
constituents to win my vote.
