It was only in South Africa that I got over this shyness, though I never completely overcame it. It was impossible for me to speak impromptu. I hesitated whenever I had to face strange audiences and avoided making a speech whenever I could. Even today I do not think I could or would even be inclined to keep a meeting of friends engaged in idle talk.
You have two people who I would classify as extremists. Donald Trump because of his behavior and Ted Cruz because of his views, leading the Republican Party.
