Unfortunately, I cannot seem to verify this, but I caught a tidbit just as I was getting to work on a left-leaning Boston talk show (Jim & Margery) and the teaser was that someone may have labeled Warren as a 'Stealth Republican'. I didn't hear anymore because I had to begin work, but if this is true, it may indicate that she has been set adrift by the DNC.
When Democrats call one of their own a Republican, it always has the same result. The end of funding, and usually the end of a campaign.
Too bad, Fauxcahontas.
