What's a "straw man" argument? Here's the explanation from Wikipedia:
"....a rhetorical technique based on misrepresentation of an opponent's position. To "set up a straw man" or "set up a straw-man argument" is to create a position that is easy to refute, then attribute that position to the opponent.
A straw-man argument can be a successful rhetorical technique (that is, it may succeed in persuading people) but it is in fact misleading, since the argument actually presented by the opponent has not been refuted.
Its name is derived from the use of straw men in combat training. It is occasionally called a straw dog fallacy  or a scarecrow argument.
Setup of a straw-man
One can set up a straw man in the following ways:
Present a misrepresentation of the opponent's position, refute it, and pretend that the opponent's actual position has been refuted .......
Here's an example of a straw man argument:
1. The Opposition aims to replace the PAP as the ruling government.
2. Can they do it better than the PAP?
3. Of course not! Compare their track records.
4. Therefore vote for the PAP.
With a little thought, it's clear that this is a nonsensical argument. The Opposition does not aim to become the ruling party. Nor does it have any chance. Prior to GE 2006, it had 2 seats out of 84 in Parliament. How could it possibly have jumped from 2 seats in Parliament to 43 seats in Parliament? That's a 2150% increase in success rate.
This could only be possible if, say, PM Lee Hsien Loong was suddenly exposed as a paedophile, Goh Chok Tong suddenly crossed over to the Workers Party, and Lee Kuan Yew suddenly announced plans to sell Singapore to Malaysia.
Actually, come to think of it, even if all these highly improbable (no, impossible) events actually occurred .... the Opposition might still not win 43 seats in Parliament.
What the Opposition aims to win a few more seats in Parliament, to supply some alternative perspectives and to act as a check and balance on the ruling party. Not to become the ruling party itself.
Naturally, it is to the PAP's advantage if Singaporeans do not realise that. Indeed the PAP is fortunate that many Singaporeans do not realise that. It is far better for the PAP, if Singaporeans believed that the Opposition aims to become, and might actually have a realistic chance, to become the ruling party. This would scare Singaporeans into voting for the PAP.
Take for example this letter in the ST Forum today:

GENERAL ELECTION 2006
Thanks to PAP victory, his family can sleep well
THE general election is finally over and families like mine can sleep well again, knowing that the People's Action Party (PAP) has been returned to power.
Congratulations to Prime Minister Lee Hsien Loong and his team for receiving a strong mandate of 66.6 per cent of the popular vote ...

The poor man. To think that he has been losing sleep for the past few weeks - over fears that the PAP might possibly NOT be returned to power. Heheh!
No resemblance to any politician in Singapore is intended.
