I only believed that because he preemptively made excuses as to why he wouldn’t attend the last one. I’m sure he’s glad he did now considering the outcome, but I wouldn’t put it past him to simply opt to not take the risk debating Harris. People are quick to forget, he also performed badly during that debate, but everyone’s focus was on Biden’s apparent sundowning. He got away with one bad performance, but he probably won’t be so lucky next time.
