Maybe she does. She sets forth a number of very good points about Trump's past and then questions whether or not he is the right person to "Make America Great Again". Given the political past of Donald Trump, he appears to have contributed in many ways to the decline of America and his history and even recent comments he has made make it clear that in many many ways he does not represent or even agree with the values that made America Great in the first place.
Perhaps you could write an essay on why Americans should take Donald Trump at his word and why, other than the platitudes he speaks at his rallies, he is the person that America needs to bring us back to greatness and exactly how (other than building that great WALL), he will be able to accomplish it.
And then see if you can do it without calling Cruz a liar.
Cruz will never be able to get his message out. He will always be on defense. Trump goes on offense.
I acknowledge we may have to hold his feet to the fire as President, but that's our job as citizens. We may very well have to raise hell and will if necessary. He is beholden to no one.
Let me see you make the case that Cruz isn't.
