Biden is not blameless. He's not the blameless victim of the big bad media. He did not just have a bad night - that performance was an absolute catastrophe, I wouldn't have allowed him to pick up my niece that night, let alone run a country. And putting it that early was HIS team's idea! Also, trying to claim he was "jet-lagged" was embarrassing given that he'd gotten back in like 10-12 days before the debate. If you cannot recover to even basic coherence after 10 days being in another country, you are not fit to be President.
And a lot of Dems didn't wait for the media's response - they had an immediate and visceral reaction on their own to Biden's performance. Which was his fault. It's HIS fault he did so badly. Not the media, not the team. It's on him. And it's not an isolated problem. It's been fairly obvious his health has been going downhill for months now. It just became very clear how bad it was during the debate.
If Biden loses, it's not as simple as the media was too mean to him. He has ****ed up, and he should not have run again. I have no confidence he will be capable of running this country by the beginning of 2029, and I doubt anyone who is taking an honest look at his health believes that. And that's what he is running for! To be President until the beginning of 2029. He should have stuck to his agreement to only serve one term. We don't need him that badly. He's not that singularly special.
