I mean, it absolutely does suck but this issue is pretty much the exact split between The Progressives and the VBNW (Vote Blue No Matter Who if somehow you've never seen that before; people who planned on voting Democrat no matter who was put up for nomination).
Eh, "VBNMW" was always a preparatory phase for progressive vote-shaming, being it was always directed squarely at progressives and Bernie supporters, and not once towards conservative Democrats and other groups that made up the 2008 PUMA movement. Notice that shit stopped dead in its tracks for the month Bernie led in the primaries, replaced by vague threats "moderates" wouldn't vote for Bernie in November.
Progressives who are bailing on Biden believe that Biden winning will be painful in the short term but ultimately will be beneficial for everyone in the long term. Basically a clear and damning signal to The DNC that we've taken your "vote for the less of evil!" shtick for the last time so either you guys make some actual changes or we're going to let you burn to the ground. Trump getting four more years is going to hurt like hell but it's the "cut off your arm to save your life" kind of situation.
They're deluding themselves into thinking that threat will work this time, unlike every election since Hubert Humphrey. Same shit establishment/corporate/conservative Dems do, repeat the tactics of the past and expect different results.
I doubt there's many Progressives who would actively want Trump to win...
Frankly, I'm one of them. I saw the eight years of normalizing and expanding upon everything Bush did, under Obama. All my life I've seen the rightward mission creep of the party, starting with the Reagan Democrats and leading us here. I've seen Biden's Senate record and understand the implications of it in how we got where we are. People can ***** about the Trump administration and the unitary executive toolkit at his disposal, but Biden was a key architect of both being his policies were what put the country in such dire straits to elect the bastard to begin with and the arsenal at his disposal.
The reality of the Biden campaign, is it doesn't offer the drastic changes in discourse and policy needed to solve for any of the problems the country faces that can still be solved, doesn't offer solutions to mitigate the harm of what can be mitigated, and doesn't offer any path forward on the problems that are no longer surmountable. Like Obama before him, the most realistic potential outcome is a full normalization of everything Trump did, by way of a complicit and largely silent press, allowing the country's marginally-privileged to continue denying the country isn't already a kleptocracy in the grips of a second Gilded Age.
A second Trump administration at least keeps the country's dirty laundry out in the open.
