They also kept their delegates and haven’t endorsed Trump. Why focus on Cruz?
Because YOU keep bring him up, injecting him in every discussion, because YOU keep posting BS about Trump. No one else on FR is doing this, no one supporting Kasick or Rubio, nor are there any reports that even hint at anything still from these two. Cruz, on the other hand, is still scheming. You as a bundler defending him, injecting him, suggests you still support him and his efforts to undermine Trump. Even saying it is party rules or with an early eye on 2020 does not make it any more acceptable.
