Trump has 48 hours to ask for a recount. He can pay for them easily, but there is no way to find votes cast for dead or folks confined in nursing homes as a result of a recount. And doing things like signature comparison would take three months to complete on the scale you suggest. Perhaps someone should ask Trump what exactly were his plans had he lost and felt the vote was rigged.
Maybe Trump should get recounts in States Hillary barely won... and before the deadline ends.
We need to be ready IF it’s necessary... Prepare for the worst - hope for the best.
