Mr Singh's campaign keeps on putting our press releases telling us how much money he is raising. So I will repeat my own experience with his campaign. I received a request for funds from Mr. Singh's campaign that really seemed to be a request to help support the NDP nationally, and it was only with some difficulty and searching that I found it was and appeal to provide financial support for Mr. Singh. I think that this was trashy and borderline unethical.
In addition, and in spite of many reputable people in the NDP backing Mr. Singh, Im concerned that he  is more flash and style than substance. As well, Im appalled that he would suggest ending universality of old age and other pensions. Absolutely contrary to the position of the NDP and social democrats worldwide.
I will be voting for either Tom Mulcair, or for Mr. Caron. I believe the NDP has to do what it can to hold on to its base in Quebec. Without support in Quebec, the NDP will never be a national party.
