When did Blue Dogs become "moderate"?

The head of the Blue Dog Democrats in the House, Mike Ross, is that Democrats are facing "a terrifying reign of their own as liberal activists and unions keep hounding moderate members out of office." (emphasis added)

Well, let's get a few things straight. Most importantly, Blue Dog does not equal moderate. In Democratic circles we have three major types. Conservatives (Blue Dogs), liberals (Kennedy was a good example), and everyone else in between who could potentially be called "moderates." But nowhere does being a Blue Dog (i.e., a right-wing Democrat) make you a moderate, any more than being a conservative (i.e., right-wing) Republican - the GOP version of the Blue Dog - make you a moderate.

It's a cute lie that people like Ross would like you to believe, and it's a cheap lie too. It's the same thing as Republicans always fighting to see who's the "real" Republican, meaning of course, the furthest to the right. And Blue Dogs play the same games. No one is "moderate" except them, they'd like you to believe. Really?

If Blue Dog Democrats in the House are "moderate" Democrats, then I'd like Ross to explain to us who the "conservative" Democrats are to the right of the Blue Dogs?  Because there are none.
