I think it's more than 50-50 that Carville has gone senile. 🙄
But my biggest question about the debate is that with CNN partisan moderators like Tapper and Bash (who will do everything they can to help Biden), what guarantee do we have that Biden will not have been fed the questions beforehand?
Since there can be no such guarantee, the only fair thing to do is to provide the questions to both candidates beforehand.
