The Donks want each voter to get a print-out of votes. This will make it much easier to run vote-buying schemes, because the voter can redeem the correctly filled out receipt for cash.
A voter reciept can serve no useful function for the purposes of a recount, because it would be patently impossible to retrieve them all, and there is no chain-of-custody over the reciepts, making any retrieved useless and suspect.
This is a bad idea, that needs to be put down, early and often.
Most of the proposals I have heard allow the voter to check and approve the receipt, but then it gets put in a locked box at the site. This would answer both of your objections.
Moreover, there are some clever proposals for creating bar codes and timestamps that authenticate the individual ballot receipts, preventing ballot box stuffing, while preserving anonymity.
I think it's a good idea, as I trust Republican politicians only marginally more than I trust the Dems.
