Can't read the email itself, but these excerpts almost seem to imply that they'd be using Google's data in order to construct this? Is this an incorrect read? Or is he just outlining how to build such a system in the abstract?

No - in the e-mail itself, he mentions that there's a mobile app field volunteers could use to update information on the voter in real-time, as they go door-to-door and canvas. Presumably it also hooks into poll databases, telephone surveys, previous voter rolls, and other data sources.

The latter. He mentions buying data from the standard marketing sources and hosting systems on AWS.
