I think it is a golden opportunity to sink Hillary’s boat. They should demonstrate how good they will be taking der Hildebeast on. In fact, they should start the debates with a bold display of unison with handshakes and a unified statement that says, “Our dispute is not with each other, but with Hillary Clinton! We have decided to make this forum a joint effort for the education of the public on who we are and who is it we oppose.”
Let the democrats take Hillary out first if that is what they plan to do. Why do the job for them - let them fight it out in their own primary (they will do a much better job of airing her dirty linen than the pubbies can right now and they will have to spend their money to do it.)
Why sink Hillary’s boat so early? Hillary has more baggage than an overloaded cargo ship. Trump is doing fine with what he is doing. Never change what is working.
