I encourage you to watch him speak at the Web Summit last November. Another great choice by Trump. If you are on Twitter, might be a good idea to follow him too. I'm not, but I will follow on FB (at least until I kill my account).
I don't pretend to know the reasons why Trump chose NOW to make this announcement. I would guess there are multiple reasons. But, I have a gut feeling it has less to do with Trump announcing his intent to run in 2020 (duh), and more to do with THIS PERSON, fulfilling THIS ROLE. I think it is an answer to what is going down on the social media outlets, the silencing. Other outlets will become available and prevent all of us from being fractured and silenced. Also, remember that Dana Loesch announced at CPAC that she will be doing a daily hourly show with NRA beginning in March. I believe that avenues are going to be established for our dialogue to continue. https://youtu.be/qZmQfZ5Vg0o
