"Let me add some info to the debate that i think will be helpful. this
is information i know first hand. working assets has funded WVWV since
it started in 2004. we've seen the research and the field plans grow
over time.

WVWV is the only voter registration group with two cycles of
replicable randomized control studies showing the impact and cost
efficiency of their mail and call based voter registration and GOTV
work. here are a few things you may not know about WVWV.

1) WVWV doesn't just target unmarried women. they target hispanics and
african americans. so it's not surprising at all that they are
targeting black voters in n.c. they've done this in partnership with
organizations like the NAACP in 2004 and National Council of La Raza
more recently. they use their methods and infrastructure from the
unmarried women work to get minorities on the roll. for instance,
field groups and funders will pay them to do mail-based voter reg on
african americans who don't live in the urban core where they can be
cost efficiently registered via door knocking and mass site
registration (at bus stops for example). so where minority voters may
be more geographically dispersed, WVWV is employed to do that
registration by mail order.

2) there is always a spike in voter registration around primaries
AFTER the registration deadline has passed. this is the best time to
register voters. research confirms this.  around primaries people are
reminded that they need to register in time for the general. WVWV has
done a lot of research in this area. they know when people are most
likely to register. unfortunately, what makes sense in registering the
largest aggregate number of voters for the general election at the
lowest cost is having a confusing effect in the N.C. primary which is
hotly contested and very charged.

3) WVWV has done a lot of research on how to layer communications so
as to have the greatest registration rate at the lowest cost from its
mail in programs. the calls increase the open rate of the envelopes
with the voter registration forms. i've seen research they have done
looking at volunteer calls before registration packets arrive v.
robocalls. also i've seen research on the effect of who the call is
from based on the gender and ethnicity of the targeted voter. are
calls from a generic voter participation organization the most
effective? or from an individual with a name and way of speaking that
is similar to the target demographic.

4) WVWV is not a clinton-associated organization. yes john podesta is
on the board, but so is mike lux and william mcnary -- both obama
people.

WVWV has made big gains in turning out african american men and
married hispanic women in the last two years. i think what is a
general election strategy which has caused a wrinkle via
misunderstanding in a primary context."

I think this explains a lot of reasoning, rationale and research and that their work should help all Democrats in November.
