In this newsgroup only the republicans survive. They drive all others
out with their insults and sheer stupidity. Mr McCall is a typical
example. In all his posts there are only insults, never any arguments
nor a technical discussion.

After a while you get fed up and you go. It is negative selection:

The more stupid you are, the better. They are showing the world how this
works with their candidate selection. There, the same principle applies
and Mr Trump wins.

I registered as a Republican in the 1980's, but since then, the
Republican Party has moved further and further away from its ideals of
the 1980's. As a consequence, I don't vote Republican very often
anymore.
