I called it half way through the last debate. I actually wrote his campaign via social media and said I was disappointed. We all worked hard, donated our money, told our friends and colleagues about him; we got him on the debate stage. What did he do up there? Nothing.
Klobuchar on the other hand seized the moment. She inspired people to the point where she went from a dark horse candidate to #3 in NH. Had Yang had that sort of debate performance he could have been in the top 4 maybe even the top 3.
He will have a seat at the table if while we the candidate is. He will be back too. Given that this was his first foray in to politics and it was at this level, he has FAR surpassed expectations. He has built an engine, a following and a brand. He will be back. If Trump wins, and I fear he will, Yang 2024 is very likely.
