Nate went further post-debate performance, knowing where Biden stands in a variety of polling and that this was the worst debate perhaps in the history of debates they was a make-or-break moment for the campaign desperate to reach a widespread audience. Biden capturing the attention of 50 million people will not happen again between now and November. For many Americans this debate, which Republicans will never let anyone forget, will be the last thing they remember.
More importantly there will be no major positive event that overrides it. That event, if it existed, already passed with Trump's conviction.
Nobody can provide me a single data-point where Biden isn't performing significantly worse than his 2020 race where he won by merely 40,000 votes across 3 battleground states. Time to face hard truths.
