No, it’s because the “take your party or go home” or “hate evangelical Christian” or “defeatist crowd-some of what we have here on FR, unfortunately” would rather vote 3rd party that is “PURE” than to see that their votes just contribute to letting commies into power!
point taken. there are those at FR that would rather destroy insufficiently pure (by their lights) conservatives than defeat liberals.
I don’t know how numerous they are, but they do make a lot of noise.
