WRU not working for block-level predictions using 2010 Census Data

[etrrosenman]

I'm working on a project that requires conducting race prediction on the 2018 voter file, and I noticed that I couldn't get any non-null predictions when running predict_race at the block level with argument year = '2010'. Digging in further, I'm actually concerned that the variables we are pulling from the Census API (PCT012I001, PCT012J001, PCT012H001, PCT012L001, PCT012M001, PCT012K001, PCT012N001, PCT012O001) are not provided at the block level for the 2010 Census.

Here is a sample query in which the API exclusively returns NULLs.
https://api.census.gov/data/2010/dec/sf1?key=2591cffde26d4140c933bd42f6faaf983a902dd7&get=PCT012I001,PCT012J001,PCT012H001,PCT012L001,PCT012M001,PCT012K001,PCT012N001,PCT012O001&for=block:*&in=state:06+county:003

I've tried a few different states/counties and I always get back NULLs.

My understanding is that the set of variables we request from the 2010 Census changed about a year age. The old set (P005003, P005004, P005010, P005006, P005007, P005005, P005008, P005009) is available at the Block level for the 2010 Census. I'm not remembering what induced the change. Can anyone help me out here?

Thanks,

Evan
