Christmas with the candidates!
I would think January 12th would be a logical date for NH to pick as well.
NH law requires them to go at least 7 days before "any similar contest", and so NH SoS has promised that, with MI going on Jan. 15, the *earliest* possible date for the NH primary would be Jan. 8th. They could go even earlier than that, but no one expects them to do so.
Oops, you're right - for a second there I thought that it was 7 days after any previous contest.
