Cruz just mis-interpreted that way. Trump supporters are some of the most informed and most engaged.
Cruz contradicted himself by saying ‘disengaged’ and ‘angry’ at the same time, also.
He sounds just as clueless as the GOPe.
Cruz is talking about voters who are disengaged from the political process of looking at the issues and records. If you have looked at Trump’s record, then he is not referring to you.
