The implication is "I support our troops, and therefore GWB, you Hanoi Jane mofo", as evidenced by the significant number of "I support President Bush and our troops" placards.

I support our troops, too. It should be a given. (In fact, I think my stance supports them more than the Hawk stance does. The longer we keep them at war, the more they get injured and die.) But the fact that they feel the need to point out that they gave $5 for a magnet (instead of, say, donating it to the VFW or VA Hospitals or whatever) is an act of claimed superiority.

And, again, the fact that 99% of the people with those magnets seem to also have "I voted against President Clinton and her husband, too" bumper stickers is not irrelevant.
