BS! They are far from panic. Do they have traitors like Mcain or Ryan condemning Hillary?
The left always remembers the endgame. They know that there is only one leader. They know any replacement leader will be in a weakened position if they jettison their current standard bearer. So the left ALWAYS chooses to unify and to support and to fight back. That is why Bill Clinton survived the impeachment. Do you remember the unanimous support from democrats, even as the claimed to be personally disgusted? Do you remember the unanimous support from leftist women's groups - even to the extent of justifying one free grope?
Elected Republicans don't have the stomach for the fight, that's why Trump is the nominee. But there is likely more to this democrat character assault on Trump. Remember back when Herman Cain ran, democrats produced women who accused him of sexual misconduct. I fully expect the next step in this program, after the debate, will be a week-long appearance of women making allegations, one or two daily. This is the core of their election strategy. They are only concerned about driving angry, irrational vajayjays to the polls. The Press is all-in with the assist.
