Looks like by now, perhaps everyone is resigned to the fact that the rumours could be true, hence I guess some people feel that keeping silent is better, some feel admitting it is better. Opinions are divided.
Personally for me speaking from political angle, silence is better because political costs are not as much or as damaging as curiousity costs. If admitting, you will stoke more stories by who the woman is, how they met or for some Sammyboy bros here, "where they did it" or "which position", the looks of both of them etc.
Look at SPP for example. Or RP, PKMS, SDA. All these parties had recent fallouts. SPP even kept the flame alive leading to 5 continuous days of news reports. But despite the fact that political costs are adding up, it still doesn't add up to a significant extent.
Keeping silent may work, if and only if, your political opponents also bahave like gentleman and keep quiet as well....Will they ???
Timing is everything....
Looking at the ongoing US GOP Presidential Primary, a lot of opponents will hit by personal scandals that happen in the past. Herman Cain was suddenly accused of sexually harassing women in the past, ONLY when he became the frontrunner. His accusers suddenly came out one by one out of nowhere just when he was winning. He was ultimately forced to drop out. Similarly, Newt Gingrich's ex-wife acts blur and keep quiet for many years. Just when he was starting to win, she suddenly jumped out, spreading all kinds of wild rumours and has her final revenge. Gingrich is now losing the race, especially the women support.
YSL and WP opponents won't stay silent forever.....
For example the husband of the involved woman should learn from Gingrich's ex-wife, quietly collecting all the evidence, secretly worked withYSL opponent and strike back forcefully 4 years later with maximum damage.
For PAP, the YSL saga is their best and perhaps only weapon to take back Hougang, Aljunied and stop their gradual expansion into neighbouring constituencies. They should use it wisely, timely and ruthlessly.
WP has the opportunity to remove that time bomb immediately...but they choose otherwise.
