"He would have lost a lot of support if he had a lot of support to lose"

Former senator Claire McCaskill said, “I think Castro’s hurt. I think he was trying to swing for the fences… I’m not sure anything tonight moved the needle except I think Castro offended people the way he did that. And it won’t surprise me if it helps Biden.”

Washington Post columnist Eugene Robinson added, “I totally agree with what Claire said.” For long stretches the debate seemed like Biden versus the fringes, and they were trying to get some sort of purchase. I think you understate the damage that Castro did to himself tonight. He would have lost a lot of support if he had a lot of support to lose. He didn’t. He had a little support. I think it’s basically over. He took a shot. It was not a good shot. And it just really went over like a lead balloon. That was a bad, bad moment for him.”
