There's no GE polls that have her kicking ass. She's been losing to at least some of the Republicans for months. Now she's losing to all of them but Trump. And that's BEFORE the right-wing smear machine kicks into action.
And of course she can't motivate the youth. She can't get all that many to donate to her campaign. She can't get many to show up to her rallies. She's just switched to hiring Brock to smear Bernie. And Chelsea to race bait. And Bill to attack. Same as 2008.
And Predictwise is not a poll. As you yourself said.
