As someone mentioned before, the establishment threw in with Cruz, not the other way around.
If they were backing trump you would say something like “it’s about time they jumped on the buss”. It certainly wouldn’t dissuade you from following trump.
Well they aren’t backing Trump ...they are backing Cruz .. no surprise , Cruz has been owned by them for a long time ... it’s funny to see you in a position of defending the GOPe’s new boy , Cruz ... I don’t envy you at all ... although however, you are welcome to join us and help elect Trump ...
