The other parties should be cohesive and united, if they want to
form an alliance, at least every mouth speaks the same story and
not splinter themselves.One thing that separates them from the
incumbent is that the latter has the benefit of the state machinery
working for them.This is the flaw of the Westminster system.Just
oil yourselves well, do not spread yourself thin,and commit too
many forces at too many fronts.
Go for one GRC at a time.let the independents/non-allied parties
challenge the rest.Speak clearly, avoid jabbering the incumbent
personality, instead, go for the jugular and attack the
policies.But preapre an alternative plan , even if its the same,
appeal to the social and human aspects of your potential
service.Always let the people know that you are their servant and
not their master.People in this climate want a bit of "power" back
in their hands, they want to know that their hands still have a
fair bit of use in them.Do not fall foul of the common mistakes ,
especially in the administrative side of your campaign, hire a
speechwriter or a proofreader to go through the speeches and your
electoral forms.Get the basics right and people are more likely to
have faith in you.If you screw up your paperwork, citizens will
play safe and vote in the incumbent again because they do not trust
your shoddiness.
You might also like to use personal experiences (remember, no
name-calling)
to spice up your campaign, use contemporary analogies to appeal to
the younger set.Campaigns should be geared to be people friendly,
not too many academically oriented stuff for the ground
activity.Those should be used to rebutt any allegation that your
sources or facts are wrong.Be kiasu and you might be a tad more
successful.
Well, thats a few points to the interested parties
