I do agree with the observations. There are bound to be some members who will not be happy with leadership in a party and these do come in as protest votes not matter who the challengers. The fact that the Poly lecturer who was with him during the CEC elections had a previous issue with WP before Chen came in does show that there are dissenters with issues that have not resolved. The big question would be if Chen mounted the challenge or was he asked to.  
My sense is that he is a nice guy but not cut out for politics no matter what the party he joins. There were numerous opportunities in the last 6 years plus the last GE to show his wares but it did not amount to much politically. 
He would however be a human interest story when he leaves WP. People would be keen to find why it did not work for him.
		
		
	 
The strange thing to me about CSM isn't whether he is cut out to be a politician, but rather all indications and vibes from him over the past 6 years imply he is not even interested in politics in the first place. That was what struck me as odd - that with such a 'disinterested' persona, he would be the banner man to challenge LTK. 
As an outsider, I can only observe what he has done/said publicly through a few avenues:
1) Parliament - Known as king of motherhood statements - a lot of vision, philosophy and principles talk. Also know more uncharitably as Captain Obvious.
2) Grassroots - My friend who stays in his ward tells me he is a very soft spoken and friendly chap. However it did not come across to him he was above board enthusiastic by WP standards or had strong grassroots organization skills in terms of quality and quantity.
3) Social media - Mainly sharing nice friendly snippets of personal anecdotes, most of the time it's not even linked to politics.
4) Party - Looks to be quite passive compared to some of the young turks who are taking on a lot of responsibilities with high visibility.
To put it in perspective, I am not putting him down for his performance. If he feels he can better contribute in the back office by taking care of his ward and using his credentials to help attract and coach a younger group of politicians, that's fine with me as well. After all, much of the expectations from the public were unilaterally projected onto him solely because of his credentials.
However, challenging someone for the top leadership position means:
1) You think WP is being led in the wrong direction
2) You disagree on status quo and propose a different vision
3) You think you are the best candidate to fulfill that vision
None of the points came out strongly when CSM challenged party leadership. In fact, we don't even know what he stands for other than the fact he seems like a friendly chap. Unless there were extenuating circumstances unknown to us, I am very disappointed with his recent actions. He is coming across no different from a lot of third rate opposition politicians - haphazardly causing drama just because he doesn't get to do things his own way and wanting to "make a statement" of displeasure. I expected better from him.
