Politicians scoring brownie points

The AHPETC case has given the politicians a lot of opportunities to score brownie points. And they appear to be quite successful and some were even thinking that the Aljunied GRC is going to return to the ruling party. Excellent jobs for the goal scorers.

I am wondering why the opposition MPs are not trying to score points on bigger issues using the same premises and arguments? There are issues like CPF, Aims, TC funds, GIC, Temasek and even issues like Roy and Amos that could arouse some emotions on the ground. But the bigger question is whether the ground will be moved by these issues or the AHPETC issues. Are the voters looking at these issues on the grounds of facts presented and how clever the arguments are? 

On the other hand, given that voters are emotional and unpredictable and at times daft when they did not do the right thing, would the voters be looking at the current controversies objectively? Or would they look above the skirmishes and at the intent and motive of the tussle. If it is the intent and purpose that they are looking at, what would be the intent and purpose of the fight? And if they could figure out the intent and motives, that it is all about politicking, would they see through all the hypocrisies and vote according to what they perceived the issues were about and not as they were told? 

And if they are looking at the intent, how would they perceive the politicians politicking for the sake of politicking instead of trying to serve the people? Intent and motive are very important factors in judging what the issues are about and not the issues themselves. If it is so simple, then the outcome of the next GE would be so predictable. 

Sometimes people vote for or against a party or candidate based on the spite factor rather than a simple right or wrong or good or bad. Sometimes too much of a good thing could turn bad and nauseating.

Has the ground shifted because of the AHPETC issues? Has the ground shifted because there are other more important issues that were swept under the carpet or not spoken about?
