@wdlindsy Right now, I think Biden is the only candidate who can't beat Trump. Anybody else would've demolished Trump last night. If Biden gave a C+ performance at that debate, we'd all be talking about how bad Trump was. Trump was asked about climate change and said "We had H2O".
Biden, not even ten minutes into the debate, lost his train of thought three times in one sentence, and ended with "we finally beat Medicare". It didn't stop there.
