I note that Limbaugh has gone on public record as saying that what went on in Abu Ghraib is a trivial matter. To balance that kind of extreme you'd perhaps need Osama Bin Laden.

The notion that you achieve balance by pitting extreme nutcases against each other is a bit questionable.

My impression is that what anywhere else would be seen as moderate or centrist views have got successfully branded, by some influential people in America, as constituting a kind of extremism.
