No, disagree on the retaliation. Warren is doing what is the very best response, and you will see all the Dems doing now: Ignoring the orange prick entirely and going to the people directly. Because any retaliation would be just giving him attention, which he desperately seeks all the time.
Also starving the beast makes him mad and he just resorts to even more stupid tweets and shout-outs at his dwindling rallies. More and more, he is looking stupider and stupider to more Americans. Disappointment grows.
Also, as stated above, Trump and the GOP have nothing left to run with except lies and name-calling. Now that they have just about **** their own nest and tried to trash the USA, they certainly don't have their "good reputation" left.
