In several states we have moved well beyond "fixable". For instance, in Texas, where they are outright saying that they are redrawing districts with the explicit goal of preventing Democrats from being represented. Not only that, they're saying they campaigned on the promise and are therefore obligated by their constituents to institute a single party state through the denial of representation of their political opponents.
I genuinely don't believe the US can be fixed anymore. We're on a slip-and-slide and far too much damage has been done to stop it. There aren't even adults left at the table to try.
