Answer: because Obama makes it look easy.

Question: why have such unprepared screw-ups like Paul, Walker and Cruz decided that they are capable of being President of the United States?

They have no idea of the character, maturity and sense of humor that lie behind Obama's ability to respond spontaneously to any situation and come out on top.

Paul and Cruz both have been groomed by their fathers to believe that they are "ordained" to win. How's that bubble working for them now?
