Kat has noticed it. So have I.
It refers to some apparent blind spots in the vision of certain GOP supporters/bloggers, namely Dave Oatney.
Maybe it's just that he sees his fave political party as incapable of error. Like excusing Rep. David Davis for protecting criminals engaging in dogfighiting 'cause the good old boys like it and seeing Biblical justification for Rep. John Duncan's legislation regarding credit.
This isn't just a knock against Oatney for it's own sake - rather that, to me and Kat, it seems he wants to eat his cake and have it too.
