Trump supporters sure didn't seem to mind when the National Inquirer was running false rumors of Cruz' having affairs. Imagine that.
Uuuuuuh....why would Trump supporters care about Cruz? Are you saying that Trump supporters should care as much about Cruz as they do about Trump? That is a very magnanimous attitude.
This response is at least in part due to the big article in DailyMail among others, which did not say so, but strongly implied that Melania was pissed at Trump and that is why she did not go to Davos.
