If I ran for president of CFC and proclaimed "vote for me because I was nominated and won poster of the year 3 years running" then you find out that I nominated myself for poster of the year, filed all of my own official documents for poster of the year, wasn't even a member of CFC one of the years, etc. etc....
You would most certainly be interested, and justifiably so! It is perfectly logical to investigate Kerry's war service because just about the only reason he is giving people to vote for him is "because I'm a war hero!" If not that, what should I consider in my vote for Kerry? His senate record

?? What he "promises" to do? I can't even figure out what he promises to do! I read about Kerry's "Plan for America" and it is basically "make it better!". That isn't a plan, it's a goal.
If someone says "vote for me because I have and will continue to fight for welfare reform" and you find out that he has done next to nothing about welfare reform in the past, you probably shouldn't vote for him. Same with Kerry.
I imagine if the rolls were reversed, and all of this controversy were over a republican canidate, there would be many pages about the vast right wing conspiracy that is America.
