Rhetorical question aside, federal elections use voter rolls that identify each potentially eligible voter and actively monitor for issues like double voting. There's no "forever stamp-holder" roll for the USPS to check.
I think they’re saying there is more evidence of fraud in stamps because of the direct monetary value, where there is no evidence that our current registration-time voting controls need to be supplemented with additional friction at voting time, because what little evidence there is of voter fraud is mostly just lies: https://www.nytimes.com/2026/09/24/us/politics/nevada-voters...
What about the marginalized communities who don't have IDs, or are you saying USPS needs more security than federal elections?
