Its not a 1-day voting day.

For 2024, vote early in case of mechanical issues or lack of ballots at the voting booths. 

Republicans will still lose unless at a minimum there's a huge effort to recruit, train and support "ballot harvesters" in every neighborhood.

I have a feeling the dem harvesters not only pickup and deliver ballots for dem voters, but they also lose ballots that were cast for non-Dem candidates.

That also happens when Liberals hold voter registration drives.  Stacks of Republican-affiliated registrations have been found in dumpsters.  Only the Dem voters were actually registered.

Unless the GOP employs the same shady tactics as the Dems, they will find it next to impossible to win another General election.
