Pat Caddell doesn't even pretend to be a Democrat anymore, really. If you didn't know that he was a "Democrat" he'd sound like any other far-right Republican. He's still an interesting guy and I like watching that Campaign Insiders show he's on, but acting like he's a Democrat is ridiculous.
As recently as 2010, he worked for Romanoff in Co.
He is a Democrat, though one that doesn't always tow the party line, which may be your problem with him. He is, from what I've seen, a good pollster and analyst.
You'll be citing Zell Miller and Joe Leiberman any minute now I suspect.
Romanoff didn't look all that conservative. I'll agree that Caddell certainly isn't an establishment Democrat, but still a Democrat.
