This isn't about Donald Trump. It's about Ted Cruz and how he sees the world. A good place to begin might be to take a look at what Cruz thinks of the venerable - wait for it - dildo.
Ted Cruz and dildos have some history that goes back to his days as Texas solicitor general when Ted summoned the full power of the Lone Star State to ban the sale of dildos.
The brief insisted that Texas, in order to protect "public morals," had "police-power interests" in "discouraging prurient interests in sexual gratification, combating the commercial sale of sex, and protecting minors." There was a "government" interest, it maintained, in "discouraging…autonomous sex." The brief compared the use of sex toys to "hiring a willing prostitute or engaging in consensual bigamy," and it equated advertising these products with the commercial promotion of prostitution. In perhaps the most noticeable line of the brief, Cruz's office declared, "There is no substantive-due-process right to stimulate one's genitals for non-medical purposes unrelated to procreation or outside of an interpersonal relationship."
In an awkward split decision (split, really, there was a dissenting judge?) the Texas court of appeals sent Cruz and his dildo pogrom packing. The bigger point is that this is a pretty telling example of how this guy thinks, where his mind is. Suddenly Trump doesn't look quite as bad and both Hillary and Bernie seem to be with the angels.
