Entirely unsurprisingly, this article never actually answers that argument.
It notes, essentially just in passing, that:
There is no doubt that the civil rights that were won over generations of struggle are under attack. The Voting Rights Act is being dismantled. An unelected Supreme Court is slashing people’s rights. The electoral system is being modified to allow the right wing to win with a minority of votes. And the rise of Trump’s ultra-right movement with its hateful and violent tendencies is of course a dangerous expression of this anti-democratic tendency – Trump himself is now openly promising a form of semi-dictatorial rule if elected.
But then it just shifts back to making the point that Biden (the article was obviously written before Harris became the candidate, but presumably the point remains) isn't left enough. It never directly addresses the existential threat that Trump poses, or the near certain fact that if Trump wins, the country will be moved so far to the right, and so many civil liberties will be stripped, that those who support the far left not only will almost certainly never get another chance to vote for a candidate of their choice, but quite possibly won't even remain free, and might not even remain alive.
Yes - it sucks to have to support yet another Overton Window shifting Democrat who almost certainly won't actually do anything to actually accomplish any truly leftist goals, but that still beats the hell out of allowing the election of a would-be tyrant who fully intends to dismantle every part of the federal government that provides any benefit at all to the people or that in any way inpedes the ability of the wealthy few to rape and pillage to their hearts' content and to invoke the Insurrection Act to deploy the military domestically to put down any protests that might result. The first option is disappointing, but the second is the literal death of US democracy and liberty.
