Why not contact a random sample of registered voters in each disputed state and ask them (1) if they voted; (2) how they voted; and (3) who did they vote for? This would provide corroborating evidence regarding the validity of the recorded vote totals and would provide an audit trail to verify the handling of their ballots.
Who could possibly be against such an effort to insure the integrity of our voting process?
Because the election is over. The only people crowing about election integrity are the people who support the side that lost. Election officials from both federal and state organizations have said that there was no evidence of voter fraud. Judges (some of them Trump appointees) are showing lawsuits the door almost as quick as they are filed. Something like 32 filed across 8 states and all of them dismissed. You and other sheep like you are questioning the integrity of the process because that's all the guy who lost and his right wing and alt-right media whores have been bleating for the past three weeks.
Trump lost. Move on. This is beyond embarrassing and quite frankly, un-American.
