Why don't you say what you mean?

Kerry's brother and "political confidant" said,"I don't know why that [last week's loss] should necessarily be it. I think it's too early to assess. But I think that he is going to continue to fight on for the values, ideals, and issues this campaign is about." We all know that Kerry's campaign didn't stand for anything except what his advisors told him would play well with the voting public. As such, Kerry must be planning to continue the fight to convince voters (nationwide as opposed to just Massachusetts which I assume he would do anyway) to like him. Why would he do that if he didn't plan to try and run again?
