Trump never, never, NEVER got over the White House Correspondents Dinner. NEVER.

47. I have to agree with your view on this

This was one of the most significant political events in US political history of the 21st century. It was the one event that needled Trump's fragile ego and unforgiving grudge holding to the point where he assembled a revenge campaign that was the most expensive and most corrupt in US history (with the most catastrophic result). Trump had never been forced to endure such humiliating ridicule probably in his whole adult life, and he had to do it on camera and in the White House of all places. The revenge he must have sworn under his breath that evening ended up souring the course of US history from that moment onward. It was not a minor incident of US history. It was more like a turning point, understood by few at the time, but recognized by the whole world afterward.

Considering the consequences, it was not a minor incident, but rather one of monumental aftermath. Had Trump not been obsessed with thought of revenge ever since that event, I am quite certain he never would have entertained the thought of running for the presidency.
