Why was Bob Rae in un-winnable Vancouer Island North riding

After my last post, I am sure to be accused of ensuring Harper will win because I am splitting the vote.  It seems as a supporter of the NDP I can only love them most of the time and then when I can actually help them at election time, I’m to vote Liberal to stop someone else from winning.  Forget that the NDP actually expresses my values, that the Liberal party doesn’t.  Just vote Liberal
