That's an interesting question and since you mention it, my suspicion is that it's in response to a disagreement with one or more frequent poster's political views some months ago. I could be wrong about this, but almost every comment I have posted in a popular forum since that time has been down voted (usually this is overridden before long except in cases of comments that probably deserve down-votes which I do occasionally make). It's not a big deal obviously but I'd like to address the poster(s) doing this (should they exist) and express my contempt for the pettiness of their approach and possibly bring moderator attention should it be warranted. But in reality, the time it took to type this post is more effort than the action deserves. It is pretty juvenile though assuming I'm seeing correctly.
