If I read a transcript of the debate, I would say Vivek won in terms of what was said. But his presentation detracts from the message.
Recap, not that it is all over (similar to a previous comment):
DeSantis was the clear winner. Scott will easily survive and move on. Haley did good except for her response to the abortion question. Christie and Pence will survive, but didn’t have a breakout evening. Ramaswamy may be liked by some, but didn’t endear himself to many. Hutchinson and Burgum were background noise.
Sorry my friend, but I find that completely ridiculous. He interrupted everyone, constantly, begging for attention, then couldn't even stay on subject over half the time. He tried to turn the whole debate into a circus. It was the most disgraceful performance I have ever seen, bar none.
