There has been zero evidence of a planned fraud at the polling location.  

I did a good job of explaining the logical fallacy of blaming any single vote (specific voter) in flipping an election.   Please let me know what you don't understand.    Anybody planning polling location fraud had better be able to alter thousands of votes in a single district to make it anywhere close to being worth the risk of getting caught.

Personally, IMO, the registration point should be were the public decides the verification needed.

As of today that is a state decision.
