I am hoping someone can help me solve this or point me in a direction. I need to know what census blocks make up the most recent Congressional Districts (115th). I have found a file that the US Census Bureau has which is the census blocks as they relate to older congressional districts (2013 I think), but not the most recent ones. The closest I can get is census tracts inside of congressional districts and I can work down from there. My understanding is that tracts can be cut by a congressional district (Which census geography boundaries do congressional districts preserve?), and I am not sure how to solve that.
I have tried an intersect, but the boundaries do not seem to work out quite correctly and I get some weird things included/excluded. A geoid relationship based text file would be ideal.
