Trump brags about his serial adultery, his fans applaud what a player he is. Ted Cruz honors a pledge he made, but not as vigorously as Trump's fans want and they call Cruz a traitor.
Trump calls Cruz's wife ugly and implies he has dirt on her, his surrogates spread false rumors that Cruz has had numerous affairs, he implies Cruz's father helped assassinate JFK, and he constantly called Cruz a liar.
It's shocking, shocking I say, that Cruz refused to wholeheartedly endorse Trump.
