I witnessed repeated problems with my sons' absentee ballots when they were in college. Once the county offices were taken over by D's, their ballots always went astray somewhere in the process. Either the ballot didn't get to them in time to be returned by the deadline, or it was never recorded as having been returned as executed. There were also irregularities at the polls, which as a poll watcher, I reported. No follow up, to the best of my knowledge.
