The organizers of January 6th bring an interesting perspective to Trump's real intentions for that day. He hijacked the rally to carry out a coup against the newly elected Pesident Biden. That is exactly what it is. It was a coup attempt by Trump. No one else is responsible for the march on the Capital. Trump diverted the "end of presidency" rally and redirected it to carry out a violent coup against the Rule of Law in the USA Constitution.
To the issue of voter fraud and mail-in ballots. The identity question is best to return to an actual signature when entering the ballot station. "Voter ID" is a very bad idea. It allows elections to become places where personal information can be exploited for many other purposes. It is simply wrong to require any person to provide proof of identity when their signature is all that is needed. Year after year in a voter record book the same signature appears when signing in to vote. There is nothing else needed. The other option is a thumb print next to the signature. If ever one runs into inappropriate activity when voting the thumb print may provide insight into who it may be.
But, im all honesty, I think we are seeing nafarious uses of the Voter ID and it's many laws. Now, lawyers are asking judges to release confidential information to a candidates campaign to determine if any of the persons voting were fraudulent. That is simply unrealistic. Voting should not be a burden so much as a responsibility. There should be a day off on election day and everyone should vote.
Occam's Razor. Simplicity is the best answer.
