I spent more than ten years helping to moderate an Internet site which had nothing to do with politics. That experience has made me a bit more sensitive about attempts by outsiders to interfere with an Internet community, because there were times during those years when my fellow moderators and I had to fend off attacks on that community, either by individuals or by small groups.
Recently, while the current scandal regarding the firing of the U.S. attorneys has been developing, I've noticed what looks to me like Republicks showing up here, trying to mess with us and with this site.
I suspect that, hurt by Democratic criticism of their regime and their heroes, and angry about any part played by us in multiplying their troubles, some of them are trying to strike back. If that's happening, I don't advocate taking any special steps to fend off the attack. I think it's sufficient to mention the possibility, so that we continue to exercise a modest amount of skepticism, either when Democratic leaders are attacked, as Majority Leader Reid was this morning, or when other outrageous statements are made by users new to this site.
