The blue state names are more religious with
Miriam / Mirayam,
Muhammad,
Aisha,
Yusuf,
Ibrahim,
Ali, and
Santino. In contrast, not a single one of the red state names are associated with any religion that I'm aware of with the possible exception of
Gracelyn, which is sort of a virtue name. The red state names are surnamey and occupational plus an apparent love of oak trees.
