One of the best articles I've read on Blue Dogs appeared recently in The Nation. Here's a couple brief excerpts:
The Blue Dogs come largely from rural and Southern districts, and often campaign by distancing themselves from the national party. Their support comes from voters who are conservative on social issues like guns and abortion. But on bread-and-butter concerns, these legislators are voting with their contributors, not their constituents.
The Blue Dogs parade as "fiscal conservatives" and "moderates," false advertising that the mainstream press mindlessly echoes. In fact, they are the epitome of a Washington captured by moneyed interests. They aren't working to ensure that healthcare reforms are paid for; they are laboring on behalf of insurance companies to protect their obscene profits. The Blue Dogs are maneuvering on behalf of Big Pharma to make sure the government won't negotiate reasonable drug prices. They're doing their best to derail reasonable tax hikes on the affluent, hikes that would make insurance affordable for working- and middle-class families. Even on the Blue Dogs' signature issue--the "pay-go" rules, which they insist must be passed into law--they exempt reductions in the estate tax on the wealthiest Americans and, of course, the cost of any military adventure whatsoever.
I encourage reading the whole thing...it's not long and it's the truth....as I know it.
