I recently observed that the conservative Southern
Democrat was making a comeback as Democrats in general have seen
their fortunes rise and the national party has decided it likes
winning better than social-issues litmus tests. The question is how
enduring this comeback will be, especially once liberals no longer
feel they need right-leaning Democrats to pad their majorities. If
this Glenn Greenwald piece essentially calling for a purge of the
Blue Dogs -- and defining that term broadly enough to include
liberal hawks -- is any indication, folks like Travis Childers had
better watch their back.
I should add that from a liberal perspective, Greenwald's
objections to the Blue Dogs make perfect sense. Conservatives would
have equal reason to be concerned if the Republican Party developed
a strategy of retaking Congress by electing Chris Shays clones in
the Northeast. (Well, that would require the GOP to have a
strategy, so it is purely hypothetical, but you get the idea.)
