Here's the part I like: Biden said "if they’re serious they ought to 'announce for president, challenge me at the convention' or rally behind him against Trump".
He's got a point. I thought the debate was a massive fuck-up, but deciding who to replace him with and then mounting a viable attempt at the replacement with that person makes a hell of a lot more sense to me than just leaning into GOP talking points about how Biden's fuckups, however bad, are definitely worse than Trump's objectively much worse fuckups.
Replace Biden? Sure, let's get fuckin busy, find a good replacement, and if doesn't work, get behind Biden or whoever the nominee is. I still think Jon Stewart is the way to do it, but that is probably a non starter of an idea. Kamala Harris is the highest polling option and realistic. Be aware that everyone who was super panicked about Biden's unsuitability will instantly pivot to panicking with concern-trolling about Kamala's unsuitability, and if you fall for it right away again and start trying to replace her, I will not have a lot of respect for you or your intelligence or pattern recognition abilities.
Keep Biden? Sure, that sounds good too. Let's get fuckin busy, and start rallying people to help him beat the end of the world in November.
Keep running in circles flapping our hands in the air about how something must be done because we're definitely going to lose in November, without offering any good alternate strategy or way to get it done? That is the option that seems unlikely to cause anything good to happen. It is, however, what a lot of the Republican aligned media seems very very committed to encouraging the Democrats to do, and for some mentally challenged reason it seems like it's winning over quite a lot of them.
