The loony right is the absolute worst when it comes to slander, innuendo & general trash journalism. It is not a monopoly of theirs however- the loony left engages in it's share of muckraking too. What I find amusing however is the sanctimonious howl from the Right about this sort of stuff- talk about people in glass houses.
Troopergate may have some legs in it, given that Palin has hired two attorneys to represent her.
