IMHO, Cruz lacks humility.
So I must assume that you are not a Trump supporter. Because if there is anyone in the race that exemplifies arrogance and lack of humility, it is Trump. That seems to be what most Trump supporters like about him!
I think Trump is very humble and I am a Trump supporter. There was an old interview...maybe 20 years old which was very informative as to personality...as well as an interview with his family and The Apprentice.
