Looks like Chafee playing the "attack dog" role isn't helping him very much. Could it be that being a useful idiot for the media and allowing them to goad you into attacking Hillary over faux scandals and using Republican talking points has backfired? Say it ain't so! Good job on being unpopular already though, even with 25% name recognition. LOL
That's not why he has net negatives. He has net negatives because hardly anybody outside of Atlas Forum has even heard of him, and those who have know him as that milquetoast Yankee weirdo that keeps jumping parties.
Nobody knows Webb or O'Malley either, and they're not in the negatives. That favorability was just among Democrats.
At this point in the race, with well over 60% not having a solid opinion of any of those three, the approvals mean very little.
