Knowing that Michael Cohen is neither likable nor credible on his own, the prosecution has built a scaffold of corroboration for his testimony. If Donald Trump–the man who told 30,000 lies while in office, according to the WaPo–decides to testify, he won’t have any such support. He will be on his own.
As a result, you have to think that Trump and his lawyers have spent the weekend arguing about whether he should testify or not. Trump thinks he is the smartest man in the world, and the ultimate salesman; he may also feel that the base wants him to vindicate himself. He will want to take the stand. His lawyers know that he will make a terrible witness and will try to explain that to him as tactfully as possible.
Who wins the tug-of-war? We’ll know early next week. One thing is for certain–the entertainment value of a Trump cross-examination would be off the charts.
