Of the five people who replied to those comments saying they wouldn’t be “falling in line,” @thirdworldtaxi, @anon15383236 and @enso have been posting anti-Hillary messages even today (much to the annoyance of those who are holding their noses to support Hillary), and @Malarkey, as far as I can see, has neither denounced nor endorsed Hillary since the primaries ended.
Only @snowlark has said that they support Clinton, and their only contribution to the discussion wasn’t to say that they wouldn’t be voting Clinton, but rather:
I don’t see anyone claiming that no one would vote Hillary, only a few people insisting that they themselves wouldn’t do so, and they seem to have stuck to their guns about it.
