What happened this weekend doesn't erase Trump's role in the political climate, the language that he uses against his political opponents which is over the top to say the least, but in some cases, points directly to violence.

“Once you go through the thought process of convincing yourself that you can be president, and then the next step that you should be president, that doesn’t leave your brain.”

This is not a message of unity in the face of what could have been a national tragedy.
