This Mexican meeting is a killshot heard around the world.
In terms of perception, look at the reaction on FR. People are all concerned about Trump’s safety. This shows that Trump has courage that many would not have and he gets the job done. Whatever it takes! That is the sign of a world class leader. This same perception is shared by tens of millions of Americans around the country. The black community is seeing this too. They see who has the courage of his conviction and who is a BS artist.
Hillary on the other hand chose not to attend this Mexican summit. She is hiding under her bed and shaking in her boots. She is deathly afraid of Mexico but won’t do anything to protect Americans from Mexican drugs and illegals.
This perception has cost her the election.
It's not a summit. Pena Nieto extended invitations to both candidates, and the intent has always been to meet with them separately. Clinton's camp has said they'll schedule a meeting later.
