Plenty of people are looking at the data, reaching the conclusion that Biden realistically can't beat Trump, and calling for an alternate strategy.

They'd say your aim was a fucking stupid one, because they see running Biden as a sure path to Trump, versus an admittedly unlikely but still possible hail-mary of running a different candidate.

My aim is to replace Biden with someone who can actually win. Bidens team is on the offensive trying to claim he's got the best shot but that's a load of hot garbage. I think you'd be surprised at how many people voted for anything not trump last time around. This time around his cognitive decline has become so blatantly obvious that by even defending it you destroy the democratic party's credibility and as a result become Trumps real enabler. The election will be decided by a few swing states and a small number of undecided voters living in those states. Telling them they are wrong about what the see and hear from Biden is gaslighting plain and simple. If democrats want to differentiate themselves as the morally superior party then lying out of fear isn't a good look. The situation is what it is. The best chance they have is to replace Biden as soon as possible. Every day that passes decreases the nominees chances. Also, I really hope they hold a primary vote because just telling voters they get Vice President Harris makes this feel less like a democracy and will definitely alienate enough voters to throw the whole election.

Final thought, as long as we have a two party system nothing will really get better. The best we can hope for is not worse. It's very telling that so many democratic congress people are afraid to challenge the party. If an elected representative is afraid to act on their conscience then it's obvious we don't have a real democracy.
