During each primary every voter is recorded as taking either a Republican or Dem ballot. The info is kept in election books. During a run-off, a new set of books has to be kept, or it’s impossible to compare the original books with the second election. I.e.: unless you switch to a new set of books, you don’t have a valid record of both the original and the subsequent election.
Maybe I'm heat addled from fenceline work but that's no clearer than before. I don't see how that squares with the Democratic Poll Book images we were looking at last night that clearly had columns designated for both 6/3 and 6/24 on the same page. Is it now being asserted that that these books were improperly used?
