I don't know what the safe guards are of the drop off sites. Are party members driving around collecting/aggregating ballots? That sounds like prime opportunity for fraud.
If a notary is required, are party members providing that service en masse? Sounds like an opportunity for fraud.
Conor is not pushing absentee balloting. He is just pretending to do so. His posts below demonstrate that.
Frank has pretended mail-in is the same as absentee voting, but that is not true. It can be the same only in the sense that you can mail in an absentee ballot. But this is a bait and switch. They want people to think that the safeguards of normal absentee balloting are in place for mail-in voting, but conor's link further below shows that is not the case. They want mass mailings to the voter roles (which are typically incorrect/outdated, and any attempt to update them is called voter suppression by the Dems).
