Every single election, Democrats say the same exact thing: This is the most important election of our lifetime. Democracy itself is at stake. This is a vital time for us to come together and fight the Republicans because, this time unlike any other, they are dangerous and unreasonable. They would have more credibility were they to say, on occasion, that that wasn’t true.
"Democracy" (unless you think our uniquely American oligarchic mashup of plutocracy, gerontocracy, and kakistocracy meets the definition) is not on the ballot. Those are Democrats. And as they have repeatedly demonstrated -- long before Biden -- they're fascism light.
Yes, some rebranding is in order. Just not the kind that they think (this applies to the Green Party in equal measure).
