Just a minor correction to the story: this past weekend, on Sunday October 21, North Carolina had only 9 out of the 100 counties open for Sunday early voting.
This weekend (October 27 & 28), the core middle weekend in the 18 days of early voting (in-person) in North Carolina, 20 counties will have early voting opportunities on Sunday, with more on Saturday (based on information from the NC State Board of Elections website):
I'll be updating the numbers coming in over the weekend, along with updating the new voter registration data file and analyzing that aspect as well.
Thanks to all for reading and following along, and especially to the new subscribers from the mention on the Rachel Maddow Show.
