I had drinks a couple of weeks ago with two guys training for the Special Forces. They were voting Bush and I asked why. The quieter, more thoughtful one told me "we were ordered to." I laughed, and he said, "no, really, we were." Apparently when they were filling out their forms for absentee ballots, they were told that they could vote for anyone they wanted as long as it wasn't Kerry.
I'd say, you are right, there's not too much Kerry support among the ranks.
