I see these Support our Troops and Pray for our Troops all over the place. Not too many Bush or Kerry stickers yet, however.
I have a "Support President Bush AND our Troops" in the same bumper sticker (given to me by a fellow freeper here)
Heard the yellow ribbon stickers are in support of W and the troops (incognito stickers) which leads me to think the same for all "support our troops/pray for our troops"
