All he needs is the large pocket watch.
Ok.... Yes and no. Hear me out...
Technically the new Republican election law in Georgia DID "shorten voting hours"..... But only for out of precinct voters.
Prior to the new law, out of precinct voters could vote at any time on election day with provisional ballots....... Now they will have to wait until after 5 pm on election day and sign an affidavit stating they would be unable to make it to their correct polling place in time. (ABC news)
So in that way, it does appear to have made voting hours shorter.... for out of precinct voters.
However......
To be fair......... I will also point out that what Biden said was not exactly what you claim he said.
According to the ABC article I read, what he actually said was "Georgia's [new] law ends voting hours early (5pm)..... And THAT does not appear to be true.
Maybe you were both confused about the details (?) idk.
