From one of several dubious readers:
I have serious doubts that the e-mailer you cited is truly a
conservative Bush voter–he’s reading from the Democratic talking
points.
Lesson number one in the seminars the Democratic Party gave to teach
their supporters how to get on conservative talk radio is for them to
tell the host they are “loyal Republicans.” They think this will get
their opinions more weight than if they tell the truth that they are
Democrats.
In fact, this was alluded to in the flyers posted at my local library
a few years ago, when the Democrats were having these seminars and
advertising for people to come.
