What?

From Commentary's review of Senator Zell Miller's new book:

Perhaps the simple if slightly cynical
answer is that if Zell Miller were
a Republican, he would not stand
out. As practically the only remaining
conservative Democrat, he is the
odd man out, ardently courted by the
Republican Senate leadership and
President Bush when they need his
vote, and sufficiently in the limelight
to be in a position to write a bestselling
book. And that may be the
saddest comment of all on what has
become of the Democratic party in
our time.
Does that make any sense? Since one jackass is exploiting his status as a conservative Democrat (really a Republican disguised as a Demcorat), it signifes a broader failure on the part of the party? I'm sorry, but I just don't see how that works. Anyway, the presence of this lousy logic in Commentary maybe the saddest comment of all on what has become of that magazine.
