He fucked up. And the DNC fucked up by allowing him to run a second time (or a first, in my book). But people are human, shockingly. They do fuck up and they do say incoherent things (you’ll understand when you get older, lol) and I’d rather have someone who spews gobblygook once in a while than someone who lies incessantly and spews gobblygook all the time.
Show me an alternative. Show me a viable path forward that ensures a second Trump presidency doesn’t happen. If you haven’t got that then there’s really nothing more to discuss. We’ll all hold our noses and vote for Biden and then raise hell to get a more reasonable candidate in 2028. Because at least then there will be a 2028 election.
