I would agree with you if the election was next month. The primary election literally isn't until June 2026 and general November 2026. There is no reason to hold onto an absolutely unremarkable guy like him. If the progressive left wants a candidate they should burn his bridges and build up an actual principled candidate.
Even IF you gave him full benefit of the doubt on the Nazi tattoo. Like, you assume he was just an edgy "23 year old child". Well, he literally had a Nazi tattoo for two decades and was too dumb to realize that? Yeah, red flag of stupidity. I wouldn't want that person driving the bus I'm riding.
I'm absolutely for people "being able to change". But that's for people that aren't my policians. Please, have a higher standard for politicians than you're favorite YouTuber or Twitch streamer.
