Boss
Take a Memo:
If the stories are false, why doesn't Cruz sue, and why is he letting Fiorina (of all people) defend his fidelity (or lack thereof)? Cruz isn't gonna be the nominee, Tex. Why are you wasting your energy defending him?
Cruz is a public political figure, his threshold for a defamation lawsuit is almost impossible. He's not "letting" anyone do anything, Carly Fiorina is free to say whatever she feels like saying... it's still a free country. Cruz has already addressed the allegations and said they were trash and had no place in politics.
Cruz will be the nominee. Get used to that and try to prepare yourself to vote for him against Hillary. Sorry if you think he is sleazy and dirty... lots of people think that about Trump too. Neither one can win the presidency with only the supporters they have in the primary. So instead of working yourself into a froth over Cruz, you need to snap out of it and understand what you're going to need to do in order to defeat Hillary Clinton... unless you LIKE Hillary and that's who you want to be the president.
