I don't think this will damage John Reid to the same degree as Mark Robinson was damaged by his scandal, if only because Robinson's scandal is a very high bar. Reid continues to claim to that the pictures were not posted by him. He claims that someone else created that account, presumably for the purpose of copying a username that he has used on other websites, so that the pictures would appear to come from Reid. If there is a lot of hostility to Reid from anti-gay Republicans, then this is actually plausible in my view.
