Closing the primary to 'independents' wouldn't hurt, either...wonder how many of those 'same day registrations' had Massachusetts or Maine plates on their cars?
Plenty did, how about the 8 charter busses with staff from Organizing America in Durham shuttling students from UNH to the town hall all day long. On the bus they “schooled” the kids on how to fill out the registration forms, had sample ballots with Othugga marked off and the ammensty letter to William Gardner, NH Sectary of State included w/stamped envelope, just sign and send to avoid prosecution.
