If you care about animals I think it is obviously the case that the best bet is to work on finding an angle that Reform will go along with. Given their poll position, the shallowness of their bench and their relatively minimal set of policy commitments, not doing this because they are “problematic” strikes me as putting low-consequence deontological considerations (you aren’t going to change the probability they win, it seems unlikely anybody cares about your endorsement) over a potentially huge opportunity for impact.
