I'm wondering if commits in the repo could be re-built from scratch because of 73b7f74. Otherwise, here is what we see in git blame for Constitution.md:

I'm not too worried about this, you can always blame an earlier commit:
https://github.com/JesseKPhillips/USA-Constitution/blame/9956c5f1b9a91f26da57e06dc3c0beb37692ba9d/Constitution.md

which is ultimately something needed as edits are made.
