Why is he waisting money on rallies? What are the purposes of them? Is anything of importance done with them or are they just a way for him to toot his own horn?
These rallies serve several purposes. 1) It gives him a platform (without a character limit) to share important information directly with US citizens. 2) It allow him to generate support for other politicians that also wish to Make America Great Again. 3) The size of the crowds in attendance prove that the #fakenews is overstating the number of people that oppose our leader. 4) It gives like-minded people an opportunity to be in the presence of one of our greatest presidents.
I could go on and on, but I'm sure that you can see the value of these events.
You should keep going until you at least make a point as to why they are needed.
