@ehBeth,
This is why we're confident. His numbers go up as his name gets around.
Many people respond positively in polling samples JUST because they know the name.
He's been on a constant upward trajectory - his primary competitor has embarrassingly low trustworthiness numbers, a morass of scandals with legs, and declining polling. Pollsters say if trends continue, Bernie is the nominee.
Thanks for links. Notice how they're being voted down? Facts and polls, not opinions? What does that say about a person...
