President Reagan was a great communicator. Even his foes admitted to that. He was coined "The Teflon President."
Trump is a great communicator. His delivery is quite different, but he clearly has his foes and rivals baffled. The "Gotcha moments" just make him more popular.
Reagan was a great communicator with the influece of the mid-west and Will Rogers.
Trump has that NYC, almost blue collar working class straight-talk delivery and lingo with a tiny bit of east coast Yiddish humor thrown in the mix.
Both were/are masters of giving a great presentation.
