would never have heard about Rajnikanth (or about any other Indian movie man; he might not even be aware that India has a big movie industry).
But if someone were to tell him about Rajnikant and show him visuals on the man acting in tamil movies, Trump would be startled to see his reflection in him !
The only difference is that while Rajnikanth makes his patent bravado talk and unique facial expressions on screen, Trump does all that in real life !
