The quote says she can't win. The insiders KNOW she can't win. Polls are garbage...since they don't even consider options. "would you vote for her if she ran for pres". Only 70% of her own party would given no other option. Thats not actually a good stat.
She has no power but that which is being given to her by the left who insist on keeping her in the spotlight. It is in their hands to make this go away.
