Trump will never have to worry about anyone plagiarizing his speeches. No one with a grain of sense would want to spew the lies and bullshit he vomits up every day.
You had better believe that oratorical contests will NOT feature contestants delivering Trump speeches.
Not a single Trump speech will appear in collections of the Greatest Speeches of the 21st Century.
If anyone collects the Trump speeches and publishes The Collected Speeches of Donald Trump, the book will be in the $1 bargain bin the day after it’s released.
