IMO.... the majority of questions answered by Vance were related to immigration. EVERYTHING, according to him, is because of the immigration problem. When asked if trump lost the election his comment was to look to the future. Would not answer the question. Hasn't he only been a senator for 2 years? His lack of experience would definitely be a major problem if the aged trump is dead or more infirmed.
I was worried about Walz but think he did better than expected. He, at least, tried to answer the questions.
