This is something that is becoming increasingly common among people who, for the sake of convenience, I'll just lump under the term of "dirtbag left". People who supported Bernie, or maybe Tulsi, but don't buy into the social justice dogma all too common on the far left. I think they realize, though perhaps only intuitively, that their movement has largely failed in the wake of the 2020 election. Additionally, they can recognize that some MAGAs and former alt-righters hold economic views that, although maybe not outright socialist, are to the left of the average republican free-market advocate or neoliberal democrat. Thus the dirtbag leftist will position themselves as "one of the good ones" and try to form some loose sort of red-brown alliance (or maybe just convert right-wingers to leftism. Whichever).
This isn't an awful strategy, but it is built on a deception. The dirtbag leftist is painting the picture of a left-wing reminiscent of old-school union dems. While union dems certainly still exist, especially in the rust belt, they are of declining relevance in the DNC, which has been fractured between neoliberals, union dems, and leftists who adhere more to intersectionalism (see also: woke). If the dems were still significantly pro-union and hadn't leaned into far-left social politics, a red-brown alliance would be perfect right now. Instead, any dirtbag leftist who wants to win over MAGAs and other assorted right-wingers are going to have to spend most of their time chasing away and/or covering for insane social justice possessed woke leftists.
