Slate mailers are generally worthless.
As a candidate for political office, one gets many, many offers
from slate mailer companies. The offers come in every few days
by mail, by email and by telephone. It has been my experience
that most slater mailer companies are just frauds and will print
anything for a buck.
Any candidate can pay and be declared the best person on earth
and the best [Democrat Republican Independent (choose one)]. Pay
more and more copies will be sent out, or larger versions, or
different colors will be used. I do not sent out slate mailers
because voters know that slater mailers are generally not worth
the paper on which they are printed.
