When I was in eighth grade, I had a seriously hardcore history teacher. I had binders upon binders with notes about actual Vietnam War battles, the Cold War, JFK's assassination, etc. I'm sure there were points at which I could guess where my teacher stood politically, but I can't really definitively say, because he never personalized or politicized any of it.
The same, it seems, cannot be said for a Virginia middle school teacher Michael Denman, who is under fire from parents after making his students do "opposition research" ... on only Republican presidential candidates. According to conservative website The Daily Caller, the eighth-graders were told to research the backgrounds and positions of Mitt Romney, Rick Santorum, Newt Gingrich, and Ron Paul ... which, okay, so far, not so strange. But after that, it got a bit bizarre.
