Statistics of Voter Search by Candidates: Logistic Regressio

[WWGD]

Hi All,
Just curious about the techniques used by current political candidates to determine potential voters. I can think of many-variable logistic regression, say, age, years of education, goes to church at least once a month (yes/no), etc. Do they use anything else?
Thanks.

I guess it won't help you that Cruz (R) thinks I'm one of his supporters living in Waterloo, Iowa?
The same does Tammy Duckworth (D) from Chicago, only that she doesn't know about Waterloo.
The same does Joni Ernst (R), Senator of Iowa.
HRC only shows up occasionally.
I think there was another one whom I have forgotten.
