Tan Kin Lian had intention to withdraw and work with TCB but didn't eventually

Mr Tan Kin Lian who had merely gotten 5% of votes in Singapore's Presidential Election 2011 commented on his blog post that he had intention to withdraw and work with his choice Mr Tan Cheng Bock but eventually decided not to because of attacks from the latter's supporters. This tells a lot of Tan Kin Lian's character.

I quote his comment

I was in favor of TCB at the start. I submitted the COE just to make sure that at least one of us was approved. Later, I changed my mind about cooperating with him, after his supporters made many personal attacks against me in the social media. If this had not happened, it would probably have been a different outcome.
I was also misled by external surveys that showed me ahead of him (which turned out to be unreliable).

A screen capture of his post in case it got lost.
