Correct me if I'm wrong, but I believe this should read "only two of the 20 officers serving with Kerry openly support his Presidential bid."
A 20 man crew on a Swift Boat would have been mighty crowded.
Article is spot-on, otherwise.
Yes, it's my understanding that that famous picture is of fellow officers, not his crew.
I think that the confusion stems from the fact that Kerry two different Swift Boats. I don't know the crew size of the typical Swift, but if you allow for crewmember rotation, 20 seems like a reasonable number.
