DNC Calling

Twice in the past month or so I've received a phone survey asking me:

if the presidential election were held today who would I vote for
is that a firm decision or is it possible I'll change my mind
am I a Democrat, Republican or independent
how strong is my party affiliation (strong, not very strong, etc)

There are a few other questions but it is basically a survey on how likely I am to vote and for whom.

I asked who sponsored the survey.  It's the DNC.
