I highly doubt it, in most cases "Reductio ad Trumperum" will remain a useful sleight of hand. This is a different matter, being "tough on China" is a bipartisan issue, it's just about showing how the other side was "doing it wrong". For instance, you could say that Trump had "no evidence" supporting his lab leak theory.
