Donate at least half of President's salary

Dear Mr. Tan,
I respect you for stating at the start of the campaign that you will be donating at least half of the President's salary towards charity and other worthy causes. You stated in clearly in statements to the media and in  you campaign website. Recently, you challenged the other candidates to state their stand on this issue.

Tan Jee Say said that he will donate the "bulk of his salary" but this statement is not clearly stated as part of his manifesto. It is only mentioned in the media interview. I hope that he will follow soon with a clear statement in writing and explain what is "the bulk".

Dr. Tan Cheng Bock had said that he will not make any pledge as it is akin to "buying votes". You can read the views of netizens on this matter here: http://sg.news.yahoo.com/blogs/singaporescene/tan-cheng-bock-won-t-pledge-donate-pay-045514750.html#mwpphu-container

And, we have not heard from Dr. Tony Tan. He is so rich that he can donate all of the salary. After all, he is getting a fat pension.

Thank you, Mr. Tan KL, for setting a good example. I hope that you will win the election and your example will be emulated by all the ministers, who are also getting get high salaries.
