Him dropping out wasn’t his biggest mistake. Him choosing to drop out months after the primary process was his biggest downfall. He basically fucked the democratic party because he couldn’t swallow his ego and drop out when it was clear his popularity among the country was dwindling even in the party itself. Every advisor he had said “hey you likely shouldn’t run again” but he stayed, Hell fucking Obama even told him “yo you aren’t going to win this”. His stubbornness to run for a second term is what killed the chances of a democratic win here.
additional note: I don’t blame him though, like I could not imagine working my entire life up to that moment, and then having to say “I wasn’t the change I wanted to be I need to let someone else take the reins”, it must have been such a blow to his self confidence. The fact that he dropped out at all was a show of strength. I don’t think him dropping out at the point he was in changed the outcome overall, the damage in my eyes was done as soon as he decided to continue with the primaries knowing he was losing support
that’s a sticky question, there’s no perfect answer sadly.
the solution of moving to a blue state is a good short term fix. However it won’t survive a long-term exposure. Eventually the federal level laws will outlaw the state level laws regarding it and their protections in the blue state won’t help them anymore. When that happens the only outcome is all red laws. We are already seeing that with him claiming that he’s going to outlaw abortion period on the federal level, which will overrule state level, an act that currently I believe would make it through the proper channels to actually get implemented as the red party currently holds half (if not all) the legislative, the entire executive, and despite it not being supposed to be possible, the judicial branches.
In a perfect world, due to everyone dispersing into the red districts, it would saturate the polls in those districts, requiring district remaps via gerrymandering to win. Unless there truly is more red voters then blue, in which case there is no solution to this problem while remaining in the US, the only valid option is either a second civil war, or moving to another country and hoping that it doesn’t spread. Neither options are ideal.
