I can get an approximation of voting age citizens for each block group, based on percentage of voting age citizens in general population per census tract.

The County Clerk was right in that the voting precinct boundaries mostly align with the 2010 Census block boundaries, but a limited amount of information is available at the block level: Counts of people and housing units, household size, age, race, ethnicity, sex, household type (e.g., presence of children), own versus rent. The 2010 vintage Census blocks and Census block group boundaries can be downloaded in shapefile format here: https://www.census.gov/cgi-bin/geo/shapefiles/index.php

Demographic data at the block level are available for download in tabular format from American FactFinder (factfinder.census.gov) but the 2010 Census is the most recent information for blocks. In order to leverage the American Community Survey data, we would have to move from blocks to block groups as the unit of analysis.
