I am in no way defending the paucity of campaign prowess of the other candidates, but they all were pretty much blindsided by a tsunami they weren’t prepared for, and pretty much (at least a few of them) will not recover from. The others are still campaigning and holding events, albeit small, cozy affairs :)
That being said, it’s hard for a candidate to get traction when the media is 24/7 Trump. Like him or not, he is a media genius and knows how to dominate the landscape and suck the oxygen out of the other campaigns. Look at what the conversation was for the Democrat debate and still days after. Do you remember anything else said or talked about besides “schlonging”?
