From the News thread..
Loads of people declare as undecided at this stage. More importantly, even more people likely haven’t decided whether to vote at all. The people who would not countenance voting for Trump aren’t going to change their mind about that because he’s still able to stand up and firehouse bullshit for 90 minutes… but they are less likely to go out and vote for Biden if they think he’s too knackered for the job.
Debates themselves don’t make all that much difference, but the ‘Biden is too old’ narrative has been impacting his support all along, and the debate supercharges it.
He’s still a decent bet to win because Trump is such a terrible candidate himself. But it shouldn’t even be close, MAGA cuntery needs to be soundly thrashed or it will continue to gain momentum.
