he’s popular as a speaker for a reason
I think he has a natural talent to listen to what gets a rise out of people, what gets a reaction, and then copy that in his own way. What he says, once transcribed to written form, is often not very intelligent. It's his mannerism and even his unique makeup and hair - that people listen to far more than his actual meaning. I find people who think Trump is a great person often have serious difficulty interpreting and understanding hard sciences like chemistry and physics... and are influenced by advertising techniques in particular ways.
A lot of people complain about traffic and commutes, but the whole personalized media industry since the iPod has turned cars into personal alone time that they don't get at home or office. I've met plenty of people who take more pride in their car and driving ability in traffic than they do with almost any positive achievement of humanity. The marketing of identity with their car and commuting lifestyle is extremely effective.
