Trump has made more than his fair share of poor personnel choices especially in the lawyer department (Ex. Powell Guiliani, etc) BUT, the fix was in here. It's more than obvious and someday, after all the "progressives have dies off, future Americans will look back at the day in shame. Dershowitz can second guess Trump's lawyers all he wants but there was no way in hell there was going to be anything other than a guilty verdict. The deep state, through the DA and judge mandated that.
There was nothing wrong with either Sidney Powell or Rudy Giuliani.
